* containerd docker hub registry mirror support

* containerd docker hub registry mirror support

* add docs

* fix typo

* fix yamllint

* fix indent in sample
and ansible-playbook param in testcases_run

* fix md

* mv common vars to tests/common/_docker_hub_registry_mirror.yml

* checkout vars to upgrade tests

(cherry picked from commit 4a8a52bad9)

* Exclude .git/ from shellcheck

If a branch name contains '.sh', current shellcheck checks the branch
file under .git/ and outputs error because the format is not shell
script one.
This makes shellcheck exclude files under .git/ to avoid this issue.

(cherry picked from commit e2467d87b6)
