ssh_auth and ssh fixes for 3006.x and 3007.x

[piterpunk]

What does this PR do?

It changes the how ssh_auth.present and ssh_auth.absent handles when the keys to be added or removed comes from a source file. This fixes:

1. The state reporting no changes even when keys are added or removed;
2. The wrongly options handling when using source file;

Added in this patch is a fix to handle keys with @ and . in their encryption types and many tests to execution module ssh.py and state module ssh_auth.py:

1. Tests all occurrences of the encryption types validation regexp in ssh_auth.py against all supported OpenSSH 8.7 key types;
2. Tests if ssh.set_auth_key_from_file is correctly called from ssh_auth.present sending the options if specified;
3. Tests if ssh.rm_auth_key_from_file is correctly called from ssh_auth.absent
4. Tests if ssh.set_auth_key_from_file and ssh.rm_auth_key_from_file correctly handles multiple keys
5. Tests if ssh.set_auth_key_from_file and ssh.rm_auth_key_from_file accept keys with @ and .
6. Tests if ssh.set_auth_key_from_file and ssh.rm_auth_key_from_file parses multiple words comments
7. Tests ssh._validate_keys against all encryption keys supported by OpenSSH 8.7, with options, without options, with simple comments, with multiple word comments and even without any comment.

I hope this set of tests are enough to prevent any regression and warranty that reading keys from source works flawlessly.
