SUMMARY

This option was introduced in #189. To my knowledge, there is no difference between MySQL and MariaDB regarding roles or when you call a user by its name alone. Same for roles.

For instance:

create user foo;
select user, host from mysql.user;
-- foo, %
show grants for foo;
-- GRANT USAGE ON *.* TO foo@%;

create role role_foo;
select user, host from mysql.user;
-- foo, %
-- role_foo, %
show grants for role_foo;

So both in MySQL and MariaDB you can omit the host.

The mysql_user plugin defaults host to localhost: host=dict(type='str', default='localhost')
So all functions will always receive a host. Maybe the option was used to bypass the default, 'localhost' and search for '%' instead of localhost ? This works because when you don't specify a host, MySQL and MariaDB will assume host is '%'.
But then, I don't get why the search for '%' is made by an option called maria_role.

I removed this option and if all tests path, I propose the get rid of it.

Sometime we must know if we are in MySQL or MariaDB, like when parsing the return of SHOW GRANTS FOR. For those cases I added a new function to the module_utils mysql.py called get_server_type().
