Clean up deprecations (#504)

* Adjust deprecation versions.

* Remove redirects that are already made in ansible/ansible's ansible_builtin_runtime.yml

* Remove modules that were moved to the google.cloud collection according to ansible/ansible's ansible_builtin_runtime.yml.

* The _info module is in google.cloud.

* The gcp doc_fragment is a copy of the one in google.cloud and is only used by one lookup. Mark as deprecated/internal.

* Remove entries of modules that no longer exist.

* Update ignore.txt.

* Try to fix test.

* Remove debug output.
