Comment 4 for bug 1199197

The patch allows '%' as a host, but more complex examples do not work:

$ trove user-create 45f6bc02-0d84-46e1-83e6-db7f3f064677 newuser mypass --host '%.com'
ERROR: The server could not comply with the request since it is either malformed or otherwise incorrect.

REQ: curl -i http://IP:8779/v1.0/549d075f78c045e984bb03e62f6ba91c/instances/45f6bc02-0d84-46e1-83e6-db7f3f064677/users -X POST -H "X-Auth-Project-Id: admin" -H "User-Agent: python-troveclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: REDACTED" -d '{"users": [{"host": "%.com", "password": "mypass", "name": "newuser", "databases": []}]}'

Per http://dev.mysql.com/doc/refman/5.5/en/account-names.html, this should work.
