Move done using gomove [1] as with the v3 and v4 moves.

The podman kube generate command can now generate a
Deployment kind when the --ype flag is set to deployment.
By default, a Pod spec will be generated if --type flag is
not set.
Add --replicas flag to kube generate to allow users to set
the value of replicas in the generated yaml when generating a
Deployment kind.
Add e2e and minikube tests for this feature.

Add the abilitiy to deploy the generated kube yaml to a
kubernetes cluster with the podman kube apply command.
Add support to directly apply containers, pods, or volumes
by passing in their names or ids to the command.
Use the kubernetes API endpoints and http requests to connect
to the cluster and deploy the various kubernetes object kinds.

Motivated to have a working `make lint` on Fedora 37 (beta).
Most changes come from the new `gofmt` standards.

map HostUsers=false to userns=auto.
One difference with the current implementation in the Kubelet is that
the podman default size is 1024 while the Kubelet uses 65536.
This is done on purpose, because 65536 is a problem for rootless as
the entire IDs space would be allocated to a single pod.

When a kube yaml has a volume set as empty dir, podman
will create an anonymous volume with the empty dir name and
attach it to the containers running in the pod. When the pod
is removed, the empy dir volume created is also removed.
Add tests and docs for this as well.

Secret was populating a generated kube as `null`. Add omitempty
so that when the volume source is not a secret, we do not print unnecessary info

add support for both creating a secret using yaml and mounting a secret as a volume given a yaml file.
Kubernetes secrets have a different structure than podman and therefore have to be handeled differently.
In this PR, I have introduced the basic usecases of kube secrets with more implementations like env secrets
to come!

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

golint, scopelint and interfacer are deprecated. golint is replaced by
revive. This linter is better because it will also check for our error
style: `error strings should not be capitalized or end with punctuation or a newline`
scopelint is replaced by exportloopref (already endabled)
interfacer has no replacement but I do not think this linter is
important.

Remove types that are not applicable for podman. This are types I do not
think we need, there is definitely more that could be removed but this
should be handled by someone who knows the k8s code better than me.

Since we do not use protobuf we can remove these field tags. This will
save some KB in the final binary size.
This change was automated with the following commands:
find pkg/k8s.io/ -type f -name "*.go" -exec sed -i -e 's/\sprotobuf\:\".*\"//g' {} +
find pkg/k8s.io/ -type f -name "*.go" -exec sed -i -e 's/\s`protobuf\:\".*\"`//g' {} +

Fix linting errors. We use different/stricter linters, instead of
skipping these packages we should fix it.
Most errors are about naming conventions, since I do not want to change
the names I added the nolint comment there. I also removed some unused
fields where the linter complained.

There is a lot of unneeded code, k8s is the by far the biggest
dependency in podman. We should remove as much as possible so that we
only have the stuff left that we use.
This is just a quick skim over the code which removes a lot of the
generated code and many packages that are now unused.
I know that this will be impossible to properly review. I will try to
make smaller changes in follow up work.
Right now this reduces about 8 MB in binary size!!!
[NO NEW TESTS NEEDED] Hopefully existing tests will catch any problems.

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.
