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. Signed-off-by: Rich Megginson <rmeggins@redhat.com>
