A number of images required for future testing are not present in GCE.
Importing them is a long proscribed process prone to errors and
complications.
Improve this situation by documenting, and encoding the majority of the
steps required. Due to the required complexity, these are clearly
identified as 'semi-automated'. This means a discerning eye is
sometimes needed to address unforeseen problems (networking issues,
format or packaging changes, etc).
Nevertheless, having these steps in writing, will reduce current and
future maintenance burden while supporting future testing needs of
RHEL, Fedora and Fedora Atomic Host.
Also:
* Add necessary configuration, scripts, and Makefile updates needed to
prepare RHEL, Fedora, & FAH cloud images for use in GCE. This
is a complex, multi-step process where the cloud image is booted
un a local user-mod qemu-kvm instance, where it can be modified.
From there, it's converted into a specific format, and imported into
GCE. Lastly, the imported raw disk data is made available as a GCE
VM image.
Note: As of this commit, the RHEL base-image builds (CentOS has native
image), however neither RHEL or CentOS cache-images build correctly.
* Left testing on FAH disabled, the GCE/Cirrus integration needs needs more
work. Specifically, the python3-based google startup script service
throws a permission-denied (as root) when trying to create a temp.
directory. Did not investigate further, though manually running the
startup script does allow the libpod tests to start running.
* Enabled Fedora 29 image to execute tests and general use.
* Utilize the standardized F28-based container image for gating
of more the intensive unit and integration testing. Update
documentation to reflect this as the standard platform for
these checks. Rename tasks with shorter names and to better
reflect their purpose.
* Cirrus: Trim unnecessary env vars before testing since the vast
majority are only required for orchestration purposes. Since most
are defined within `.cirrus.yml`, it's a good place to store the
list of undesirables. Since each of the cirrus-scripts runs in
it's own shell, unsetting these near the end will have no
consequence. Also trim down the number of calls to show_env_vars()

The packer tool takes JSON as input for the details of producing VM
images to be used for PR CI-testing. JSON is not a very human-friendly
format, without support for comments and frequently containing lots of
duplicate data.
Fix this by using a Makefile + simple python one-liner to convert
from a human-friendly YAML format into packer-native JSON. This allows
use of anchors/aliases to reduce duplication, and allows inline comments
for easier maintainability. This also allows separating the 'test'
action from the 'build' action, for earlier and better syntax problem
detection.
Lastly, there are some minor ``lib.sh`` and ``integration_test.sh``
updates to support future work, and slightly improve the build and
test environments.

containers inside pods need to make sure they get /etc/resolv.conf

Per discussion with Dan, it would be better to automatically
handle potential runtime errors by automatically syncing if they
occur. Retaining the flag for `ps` makes sense, as we won't even
be calling the OCI runtime and as such won't see errors if the
state desyncs, but rm can be handled automatically.
The automatic desync handling code will take some additional work
so we'll land this as-is (sync on ps is enough to solve most
desync issues).

With the changes made recently to ensure Podman does not hit the
OCI runtime as often to sync state, we can find ourselves in a
situation where the runtime's state does not match ours.
Add a --sync flag to podman rm to ensure we can still remove
containers when this happens.

Add support for podman volume and its subcommands.
The commands supported are:
podman volume create
podman volume inspect
podman volume ls
podman volume rm
podman volume prune
This is a tool to manage volumes used by podman. For now it only handle
named volumes, but eventually it will handle all volumes used by podman.

podman login reg.io/username/image works as well now. It picks
the registry and checks for authentication, if none exist it
will prompt for username and password.
If the credentials exist but are not valid, it will prompt the
user for new valid credentials.

Callers that only care about the IDs should try to convert the
identifier to an integer before calling the Get* functions, so they
can save the cost of hitting the filesystem and maybe or maybe not
finding the other fields (User.Name, etc.). But callers that *want*
the other fields but only actually need the ID can, with this commit,
just call the Get* function and ignore ErrNo*Entries responses:
user, err := lookup.GetUser(mount, userIDorName)
if err != nil && err != ErrNoPasswdEntries {
return err
}
Previously, they'd have to perform their own integer-conversion
attempt in Get* error handling, with logic like:
user, err := lookup.GetUser(mount, userIDorName)
if err == ErrNoPasswdEntries {
uuid, err := strconv.ParseUint(userIDorName, 10, 32)
if err == nil {
user.Uid = int(uuid)
}
} else if err != nil {
return err
}

When an image config sets config.User [1] to a numeric group (like
1000:1000), but those values do not exist in the container's
/etc/group, libpod is currently breaking:
$ podman run --rm registry.svc.ci.openshift.org/ci-op-zvml7cd6/pipeline:installer --help
error creating temporary passwd file for container 228f6e9943d6f18b93c19644e9b619ec4d459a3e0eb31680e064eeedf6473678: unable to get gid 1000 from group file: no matching entries in group file
However, the OCI spec requires converters to copy numeric uid and gid
to the runtime config verbatim [2].
With this commit, I'm frontloading the "is groupspec an integer?"
check and only bothering with lookup.GetGroup when it was not.
I've also removed a few .Mounted checks, which are originally from
00d38cb3 (podman create/run need to load information from the image,
2017-12-18, #110). We don't need a mounted container filesystem to
translate integers. And when the lookup code needs to fall back to
the mounted root to translate names, it can handle erroring out
internally (and looking it over, it seems to do that already).

Instead of storing the runtime's file lock dir in the BoltDB
state, refer to the runtime inside the Bolt state instead, and
use the path stored in the runtime.
This is necessary since we moved DB initialization very far up in
runtime init, before the locks dir is properly initialized (and
it must happen before the locks dir can be created, as we use the
DB to retrieve the proper path for the locks dir now).
