72f4f389f0 Adds support to preserve auto update labels in generate and play kube
In the case of generate kube the auto-update labels will be converted into kube annotations and for play kube they will be converted back to labels since that's what podman understands

1e255b6df9 Generate Kubernetes PersistentVolumeClaims from named volumes
Fixes #5788

This commit adds support for named volumes in podman-generate-kube.
Named volumes are output in the YAML as PersistentVolumeClaims.
To avoid naming conflicts, the volume name is suffixed with "-pvc".
This commit adds a corresponding suffix for host path mounts.
Host path volumes are suffixed with "-host".

57e8c66322 Do not leak libpod package into the remote client
Some packages used by the remote client imported the libpod package.
This is not wanted because it adds unnecessary bloat to the client and
also causes problems with platform specific code(linux only), see #9710.

The solution is to move the used functions/variables into extra packages
which do not import libpod.

This change shrinks the remote client size more than 6MB compared to the
current master.

[NO TESTS NEEDED]
I have no idea how to test this properly but with #9710 the cross
compile should fail.

0e36e65eaa Allow users to generate a kubernetes yaml off non running containers
Currently if you attempt to create a kube.yaml file off of a non running
container where the container runs as a specific User, the creation
fails because the storage container is not mounted. Podman is supposed to
read the /etc/passwd entry inside of the container but since the
container is not mounted, the c.State.Mountpoint == "".  Podman
incorrectly attempts to read /etc/passwd on the host, and fails if the
specified user is not in the hosts /etc/passwd.

This PR mounts the storage container, if it was not mounted so the read
succeeds.

c995b54607 generate kube: handle entrypoint
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`.

ca0dd76bf3 Honor custom DNS in play|generate kube
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.

8489dc4345 move go module to v2
With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules.  While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.

Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`.  The renaming of the imports
was done via `gomove` [1].

f269be3a31 add {generate,play} kube
Add the `podman generate kube` and `podman play kube` command.  The code
has largely been copied from Podman v1 but restructured to not leak the
K8s core API into the (remote) client.

Both commands are added in the same commit to allow for enabling the
tests at the same time.

Move some exports from `cmd/podman/common` to the appropriate places in
the backend to avoid circular dependencies.

Move definitions of label annotations to `libpod/define` and set the
security-opt labels in the frontend to make kube tests pass.

Implement rest endpoints, bindings and the tunnel interface.

dd81a44ccf remove libpod from main
the compilation demands of having libpod in main is a burden for the
remote client compilations.  to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.

this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

ebf48ff459 Only include ports in one container in Kube YAML
This likely broke when we made containers able to detect that
they shared a network namespace and grab ports from the
dependency container - prior to that, we could grab ports without
concern for conflict, only the infra container had them. Now, all
containers in a pod will return the same ports, so we have to
work around this.
