role (Identity) can be just white character

[Martin Pavlásek]

Admin - Identity - Roles, Create role page:

The form allows to create role that contains just one space. if I've tried to create role with name ' some spaces in the end ', the my input was truncated by whitespaces from both sides - as I expected, but as I realized, it wasn't applied in case just one space.

Seems to be the same hitting keystone directly

keystone role-create --name " "
+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| id | 711cef7a1baa4f5e84e8ba0b73fa698c |
| name | |
+----------+----------------------------------+

so keystone server does validation of role name, but only for v3 calls, not v2.

even though we will be deprecating v2, maybe we should look into adding it since it's not much effort.
