* Remove use of repo_depth_url
* Use native yaml

* If the hash is valid (full-length) but doesn't exist, git returns 128 instead of 1.
* Ensure git doesn't use hardlinks for shallow clones
* Fix UnboundLocalError remote_head in git
Fixes#5505
The use of remote_head was a leftover of #4562.
remote_head is not necessary, since the repo is unchanged anyway and
after is set correctly.
Further changes:
* Set changed=True and msg once local_mods are detected and reset.
* Remove need_fetch that is always True (due to previous if) to improve
clarity
* Don't exit early for local_mods but run submodules update and
switch_version
* Add test for git with local modifications
* Add tag verification test (ansible-modules-core PR 2654)
* Fix typo
* Use smaller repo for testing, add dependency control
* Test is gpg exists before running git signing tasks
* Correct the test conditionals so that gpg1 is tested
