Implement podman secret create, inspect, ls, rm
Implement podman run/create --secret
Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit

When resolving the workdir of a container, we may need to create unless
the user set it explicitly on the command line. Otherwise, we just do a
presence check. Unfortunately, there was a missing return that lead us
to fall through into attempting to create and chown the workdir. That
caused a regression when running on a read-only root fs.

The allocated `tmpNetworkStatus` must be allocated with the length 0.
Otherwise append would add new elements to the end of the slice and
not at the beginning of the allocated memory.
This caused inspect to fail since the number of networks did not
matched the number of network statuses.

The spec of a Kube Container has a `Command` and `Args`. While both are
slices, the `Command` is the counterpart of the entrypoint of a libpod
container. Kube is also happily accepting the arguments to as following
items in the slice but it's cleaner to move those to `Args`.

instead of using the --macvlan to indicate that you want to make a
macvlan network, podman network create now honors the driver name of
*macvlan*. Any options to macvlan, like the parent device, should be
specified as a -o option. For example, -o parent=eth0.
the --macvlan option was marked as deprecated in the man page but is
still supported for the duration of 3.0.

when creating kubernetes yaml from containers and pods, we should honor
any custom dns settings the user provided. in the case of generate kube,
these would be provided by --dns, --dns-search, and --dns-opt. if
multiple containers are involved in the generate, the options will be
cumulative and unique with the exception of dns-opt.
when replaying a kube file that has kubernetes dns information, we now
also add that information to the pod creation.
the options for dnspolicy is not enabled as there seemed to be no direct
correlation between kubernetes and podman.

Make sure to write error from conmon on the hijacked http connection.
This fixes issues where errors were not reported on the client side,

To future generations: I am sorry. The code is complex, and there are

complexity on top but I don't have a good idea of how to reduce

A container's workdir can be specified via the CLI via `--workdir` and
via an image config with the CLI having precedence.
Since images have a tendency to specify workdirs without necessarily
shipping the paths with the root FS, make sure that Podman creates the
workdir. When specified via the CLI, do not create the path, but check
for its existence and return a human-friendly error.
NOTE: `crun` is performing a similar check that would yield exit code
127. With this change, however, Podman performs the check and yields
exit code 126. Since this is specific to `crun`, I do not consider it
to be a breaking change of Podman.

podman-remote search had some FIXMEs in tests that were failing.
So I reworked the search handler to use the local abi. This
means the podman search and podman-remote search will use the
same functions.
While doing this, I noticed we were just outputing errors via
logrus.Error rather then returning them, which works ok for
podman but the messages get lost on podman-remote. Changed
the code to actually return the error messages to the caller.
This allows us to turn on the remaining podman-remote FIXME
tests.

There was a potential race where two handlers could be added at
the same time. Go Maps are not thread-safe, so that could do
unpleasant things. Add a mutex to keep things safe.
Also, swap the order or Register and Start for the handlers in
Libpod runtime created. As written, there was a small gap between
Start and Register where SIGTERM/SIGINT would be completely
ignored, instead of stopping Podman. Swapping the two closes this
gap.

Commit(fe3faa517e1b) introduced a lock file for network create/rm calls.
There is a problem with the location of the lock file. The lock file was
stored in the tmpdir. Running multiple podman network create/remove
commands in parallel with different tmpdirs made the lockfile inaccessible
to the other process, and so parallel read/write operations to the cni
config directory continued to occur. This scenario happened frequently
during the e2e tests and caused some flakes.
Fixes#9041

Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.

This implements support for mounting and unmounting volumes
backed by volume plugins. Support for actually retrieving
plugins requires a pull request to land in containers.conf and
then that to be vendored, and as such is not yet ready. Given
this, this code is only compile tested. However, the code for
everything past retrieving the plugin has been written - there is
support for creating, removing, mounting, and unmounting volumes,
which should allow full functionality once the c/common PR is
merged.
A major change is the signature of the MountPoint function for
volumes, which now, by necessity, returns an error. Named volumes
managed by a plugin do not have a mountpoint we control; instead,
it is managed entirely by the plugin. As such, we need to cache
the path in the DB, and calls to retrieve it now need to access
the DB (and may fail as such).
Notably absent is support for SELinux relabelling and chowning
these volumes. Given that we don't manage the mountpoint for
these volumes, I am extremely reluctant to try and modify it - we
could easily break the plugin trying to chown or relabel it.
Also, we had no less than *5* separate implementations of
inspecting a volume floating around in pkg/infra/abi and
pkg/api/handlers/libpod. And none of them used volume.Inspect(),
the only correct way of inspecting volumes. Remove them all and
consolidate to using the correct way. Compat API is likely still
doing things the wrong way, but that is an issue for another day.

Podman defers stopping the container to the runtime, which can take some
time. Keeping the lock while waiting for the runtime to complete the
stop procedure, prevents other commands from acquiring the lock as shown
in #8501.
To improve the user experience, release the lock before invoking the
runtime, and re-acquire the lock when the runtime is finished. Also
introduce an intermediate "stopping" to properly distinguish from
"stopped" containers etc.

need to import Driver. And simplify the driver code while we're
