`podman kube play` can create pods and containers from YAML
read from a URL poiniting to a YAML file.
For example: `podman kube play https://example.com/demo.yml`.
`podman kube down` can also teardown pods and containers created
from that YAML file by also reading YAML from a URL, provided the
YAML file the URL points to has not been changed or altered since
it was used to create pods and containers

Much like --cidfile (#15414), --pod-id-file has two meanings.
One is used in pod-related commands, one in container ones.
Both meanings read the file, so the read/write split used
in --cidfile is not applicable here.
podman-pod-create keeps its --pod-id-file option because
that one cannot be refactored: that's the only command (now)
that writes a pod-id file.
Reviewable using hack/markdown-preprocess-review but I
did take some liberties with the #### args because they
were wrong. And, since I had to much with the description
text anyway (resulting in diffs), I also took the liberty
of cleaning up a double space.

I've been doing the man-page cleanup distractedly, while
fighting other fires, and submitted some crap:
* #15339: I used single angle brackets, not double
* #15407: I only refactored --cert-dir from some man pages, not all
Easy to review with hack/markdown-preprocess-review, because all the
removed texts are identical. The only diff is that container-certs.d
is now a link.
Sorry about that. I'm going to spend more time being careful.

There are two meanings: one writes a cidfile, the other reads.
Split into two .md files.
This can be reviewed with hack/markdown-preprocess-review .
The main differences you'll see are all in cidfile.read:
1) I use the <<subcommand>> feature. This works nicely for
kill, pause/unpause, and stop. It works less nicely for
rm, because the man page will show "...and rm the container"
(a human might prefer to see "REMOVE the container"). Given
the benefit of this cleanup, I think this is a fine tradeoff.
2) I choose to include the "multiple times" text even on man pages
where it wasn't present before. I tested to make sure it works.
3) The #### line I choose is IMHO the best one.
Minor differences:
* I believe the "remove the container" text in podman-kill
and podman-stop is a copy/paste error. This PR fixes it.
* The only differences between the cidfile.write texts is
the #### line (my version is best) and a final period.

Refactor the --creds option. I went with the one in podman-pull
The main difference between all of them is the '####' line,
differences in the param descriptions. podman-pull had the
clearest one.
This is another one that hack/markdown-preprocess-review is
good for reviewing.

After pulling/creating an image of a foreign platform, Podman will
happily use it when looking it up in the local storage and will not
pull down the image matching the host platform.
As discussed in #12682, the reasoning for it is Docker compatibility and
the fact that user already rely on the behavior. While Podman is now
emitting a warning when an image is in use not matching the local
platform, the documentation was lacking that information.

Refactor the --authfile option.
My suggestion for review:
1) run hack/markdown-preprocess-review and immediately Ctrl-Q to
quit out of diffuse, which is completely unusable for this
many files; then
2) cd /tmp/markdown-preprocess-review.diffs/authfile
- this is the directory created by the review script
3) rm podman-image-sign* podman-log* podman-search.1.md.in
- because they're essentially identical to podman-create
4) rm podman-manifest-* podman-push.*
- because they're 100% identical to podman-kube-play
5) rm podman-kube-play*
- because it's apart-from-whitespace identical to podman-build
(use "wdiff" to confirm)
6) rm podman-auto-update*
- because that's the one I chose (hence == zzz-chosen.md)
(You should obviously run your own diff/cmp before rm, to confirm
my assertions about which files are identical).
After all that, you have a manageable number of files which
you can scan, read, diff against zzz-chosen.md, even run diffuse.
This option is IMHO the poster child for why we need this kind
of man page refactoring.

Refactor the --annotation option, but only between podman create,
kube play, and run.
This does not include:
* podman build:
- usage is in terms of images, not containers/pods
* manifest add, manifest annotate:
- usage is in terms of images, not containers/pods
- also, wording is slightly different

Smaller, more reviewable chunks.
This is just one option, --arch. Future PRs may, if the reviewing
is easy, include multiple options. This one includes fixes to
the preprocessor script, though:
* big oops, I was not handling '<<something pod|something>>'
where 'pod' appears other than the beginning of the string.
* I was also not handling 'container<<| or pod>>', where one
side was empty.
* Behavior change: <<subcommand>>, on podman-pod-foo,
becomes just 'foo' (not 'pod foo'). This will be useful
in a future PR where we refactor --pod-id-file.

Insisting on “DCO” imposes formalities, that serve self-purpose. One cannot
assume that the submitter has time or will to read texts about symbolism in

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

Followup to #15174. These are the options that are easy(ish)
to review: those that have only drifted slightly, and need
only minor tweaks to bring back to sanity. For the most part,
I went with the text in podman-run because that was cleaned up
in #5192 way back in 2020. These diffs primarily consist of
using '**' (star star) instead of backticks, plus other
formatting and punctuation changes.
This PR also adds a README in the options dir, and a new
convention: <<container text...|pod text...>> which tries
to do the right thing based on whether the man page name
includes "-pod-" or not. Since that's kind of hairy code,
I've also added a test suite for it.
Finally, since this is impossible to review by normal means,
I'm temporarily committing hack/markdown-preprocess-review,
a script that will diff option-by-option. I will remove it
once we finish this cleanup, but be advised that there are
still 130+ options left to examine, and some of those are
going to be really hard to reunite.
Review script usage: simply run it (you need to have 'diffuse'
installed). It isn't exactly obvious, but it shouldn't take more
than a minute to figure out. The rightmost column (zzz-chosen.md)
is the "winner", the actual content that will be used henceforth.
You really want an ultrawide screen here.

implement a new command `podman generate spec` which can formulate a json specgen to be consumed by both the pod
and container creation API.
supported flags are
--verbose (default true) print output to the terminal
--compact print the json output in a single line format to be piped to the API
--filename put the output in a file
--clone rename the pod/ctr in the spec so it won't conflict w/ an existing entity
