* formatting
make the PEP8 check happy
* mysql_user and mysql_role: fix granting privileges when only the GRANT OPTION needs to be added
* mysql_user and mysql_role: log some updated privileges; explain integration test blind spot
* mysql_user and mysql_role: don't grant too much privileges
If only the grant option needs to be granted, at least one privilege needs to be granted to get valid syntax. USAGE is better for that than the existing privileges, because unwanted privileges would be re-added after revokation.
