ipatests: add XMLRPC test for user-add when UPG plugin is disabled
Add a new XMLRPC test in test_user_plugin:
- disable the UPG plugin
- create a user without the --gid parameter
as the default group for new users is not POSIX (ipausers), the
command is expected to fail
- create a user with the --gid parameter
The provided gid is used and command is expected to succeed
- create a user with the same name as an existing group
As the UPG plugin is disabled, the user creation will not trigger
the creation of a group with the same name, and command is
expected to succeed
- re-enable the UPG plugin for other tests
