* mysql_user: Fixed change detection with append_privs (#69)
Prior to this change, mysql_user with append_privs would attempt to make
a change even if the current privileges were a superset of the new
privileges (shouldn't require any action).
* Fixed unrelated mysql_replication doc causing failures in CI
* Added fragments and check_mode tests
* Expanded priv append tests to cover additional case
* initial commit
* removed remaining references to community.general
* enabled integration pipeline
* switched from preconfigured replication topology to simple multinode install
* updated version from 1.0.0 to 0.1.0
