test: use `T.TempDir` to create temporary test directory
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.

Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
	defer func() {
		if err := os.RemoveAll(dir); err != nil {
			t.Fatal(err)
		}
	}
is also tedious, but `t.TempDir` handles this for us nicely.

move k8s deps into podman
We only need a small part of the k8s dependencies but they are the
biggest dependencies in podman by far. Moving them into podman allows us
to remove the unnecessary parts.

Alban Bedel c59eb6f12b play kube: add support for env vars defined from secrets
Add support for secretRef and secretKeyRef to allow env vars to be set
from a secret. As K8S secrets are dictionaries the secret value must
be a JSON dictionary compatible with the data field of a K8S secret
object. The keys must consist of alphanumeric characters, '-', '_'
or '.', and the values must be base64 encoded strings.

Alban Bedel e5ff694855 play kube: support optional/mandatory env var from config map
In K8S the pod creation fails if an env var reference a non existing
config map key. It can be marked as optional, but per default it is
mandatory. Podman on the other hand always treat such references as
optional.

Rework envVarsFrom() and envVarValue() to additionaly return an error
and add support for the optional attribute in configMapRef and
configMapKeyRef.

Alban Bedel 9f92b8b0d8 play kube: prepare supporting other env source than config maps
Rework envVarsFromConfigMap() and envVarValue() to simplify supporting
other env sources than config maps. For this we pass the whole spec
generator options struct as parameter instead of just the config maps
list. Then we rename envVarsFromConfigMap() to envVarsFrom() and in
envVarValue() we reposition the loop over the config maps to only run
it when a configMapRef element exists.

baude 72ec8b0aa2 migrate play kube to spec gen
we need to migrate play kube away from using the old container creation
method.  the new approach is specgen and this aligns play kube with
container creation in the rest of podman.
