Add 2 options to runcontainer.sh

[nhosoi]

New options:

• --extra-rpm : specifies an additional rpm package to install in the container. Default to none. E.g., --extra-rpm diffutils --extra-rpm sudo
• --extra-skip-tag : specifies a tag to skip. Default to none. E.g., --extra-skip-tag "tests::use_selinux_role"

Sample command line using the new options:

tox -e container-ansible-core-2.15 -- --erase-old-snapshot --extra-rpm diffutils \
--extra-skip-tag "tests::use_selinux_role" --parallel 4 \
--image-name centos-9 tests/tests_*.yml

Duration per parallel count:

==> /tmp/logging_tests.out.parallel_1 <==
  container-ansible-core-2.15: commands succeeded
  congratulations :)

The tests were executed on my laptop. We could see the improvement up to parallel == 4.

Shall I add tests::use_selinux_role tag to the other roles as in this pr for the logging?
linux-system-roles/logging#338
Or we'd better leave it to each role owner?

Shall I add tests::use_selinux_role tag to the other roles as in this pr for the logging? linux-system-roles/logging#338 Or we'd better leave it to each role owner?

I would prefer to use the tag named tests::uses_selinux because a test might not use the selinux role, but might use one of the selinux modules or commands directly (like the selinux role itself)

You can submit PRs for all of the roles if you like - I don't think individual role owners will mind, in fact I think they will welcome the help.
