This is a backport of PR #971 as merged into main (027700c).
SUMMARY
Was going trough the list with issues and found 958; which seemed a quick fix.
What I fixed with with this PR:
Added support for copying files to init containers.
Fixed the format message when an exec is failing for a pod (the order was wrong).
Added a check if the container that you try to run copy for is started.
ISSUE TYPE
Bugfix Pull Request
COMPONENT NAME
copy.py module
ADDITIONAL INFORMATION
Some testing.
Verify that the pod does not exist:
kubectl -n default get pod/yorick
Output:
Error from server (NotFound): pods "yorick" not found
Run the playbook to create the file, create the deployment, wait for the init container to be ready, copy the created file to the init container, cat the copied file (using kubernetes.core.k8s_exec) that is now in the init container and try to copy the created file to the (not started) container (which fails - to see the new error message for it):

The GHA environment has difficultly generating entropy. Trying to read
from /dev/urandom just blocks forever. We don't care if the random data
is cryptographically secure; it's just garbage data for the test. Read
from /dev/random, instead. This is only used during the k8s_copy test
target.
This also removes the custom test module that was being used to generate
the files. It's not worth maintaining this for two task that can be
replaced with some simple command/shell tasks.
