Enhance support of tls_requires in mysql_user and mysql_info

[laurent-indermuehle]

SUMMARY

I refactored the get_tls_requires method with separate implementations for MySQL and MariaDB.
The solution for MariaDB turned out to be incompatible with MySQL.

I fixed the integration tests for mysql_info and added test users with TLS to assert that everything is working correctly.

This chang enable using the output of mysql_info: {filter: users_info} and passing it to mysql_user to achieve idempotent execution even if the user has TLS options.

I encountered an issue with MySQL 8 refusing to remove SSL and X509 when tls_requires was passed an empty value. I'm unsure why this test passed previously. Perhaps it was due to adding a sanitized method during this PR? I admit that I didn't put much effort into MySQL (even though it consumes 80% of my time...). I hope I successfully fixed that too.
