ci: skip most CI checks if title contains citest skip [citest_skip]

When we submit a PR for a CI update or docs, we do not want to start CI checking
for ansible-lint, qemu, etc.  When we are doing CI updates to 30 or more
roles, this fires off a lot of unnecessary tests, which sometimes causes the
linux-system-roles org in github to be throttled.

When submitting a PR that can skip ci, use "[citest_skip]" in the PR title.
