If the k8s yaml has volumes from a configmap, play kube
will now create a volume based on the data from the
configmap and volume source and set it to the right path
in the container accordingly.
Add tests for this and update some test for ENV from configmap.

Kubernetes has a concept of init containers that run and exit before
the regular containers in a pod are started. We added init containers
to podman pods as well. This patch adds support for generating init
containers in the kube yaml when a pod we are converting had init
containers. When playing a kube yaml, it detects an init container
and creates such a container in podman accordingly.
Note, only init containers created with the init type set to "always"
will be generated as the "once" option deletes the init container after
it has run and exited. Play kube will always creates init containers
with the "always" init container type.

Following PR adds support for `kubectl` like `pod logs` to podman.
Usage `podman pod logs <podIDorName` gives a stream of logs for all
the containers within the pod with **containername** as a field.
Just like **`kubectl`** also supports `podman pod logs -c ctrIDorName podIDorName`
to limit the log stream to any of the specificied container which belongs to pod.

e2e test failures are rife with messages like:
Expected 1 to equal 0
These make me cry. They're anti-helpful, requiring the reader
to dive into the source code to figure out what those numbers
mean.
Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I
don't know if it spits out a better diagnostic (I have no way
to run e2e tests on my laptop), but I have to fantasize that
it will, and given the state of our flakes I assume that at
least one test will fail and give me the opportunity to see
what the error message looks like.
THIS IS NOT REVIEWABLE CODE. There is no way for a human
to review it. Don't bother. Maybe look at a few random
ones for sanity. If you want to really review, here is
a reproducer of what I did:
cd test/e2e
! positive assertions. The second is the same as the first,
! with the addition of (unnecessary) parentheses because
! some invocations were written that way. The third is BeZero().
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go
! Same as above, but handles three non-numeric exit codes
! in run_exit_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
! negative assertions. Difference is the spelling of 'To(Not)',
! 'ToNot', and 'NotTo'. I assume those are all the same.
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
! negative, old use of BeZero()
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go
Run those on a clean copy of main branch (at the same branch
point as my PR, of course), then diff against a checked-out
copy of my PR. There should be no differences. Then all you
have to review is that my replacements above are sane.
UPDATE: nope, that's not enough, you also need to add gomega/gexec
to the files that don't have it:
perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}'))

UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places
UPDATE 4: skip a test due to bug #10935 (race condition)

Reason: to catch errors before they surface in RHEL.
One of the Ubuntus is specially crafted to run with cgroups v1

close as we can come in our CI environment, and I suspect it

Also: play kube limits test: skip on all rootless, not just

container, we report an error to them.

Since the user specified the correct name and the container is in storage we

user.
This change will just remove the container from storage. If the container

The play kube test suite has many different cases to cover, and should only grow in coverage over time
The old design was difficult to extend, and there was lots of duplicated code.
The largest pain point was the Container struct needed to be changed often, and doing so caused changes every test case
Instead, adopt the `withOption` idiom. Now, adding a new option for customizing just involves adding a new withOption function, and changing the struct definition and initialization in one place.
