Removes NoModule from the base testcase

Only test_keystoneclient actually uses NoModule so there is no reason
for all testcases to inherit it's functionality.

Enhance tests for delete_grant no user/group

There were no tests to show that when delete a grant and the
target user or group doesn't exist then it fails with NotFound.

Allow delete user or group at same time as role

If a user was deleted at the same time as a role that the user has
been granted the server may respond with a 404 Not Found because the
user doesn't exist when the Keystone server checks for it.
Whether there's an error or not depends on timing.

Also, if the system is configured to use LDAP as the identity
backend, the user may be removed directly from the LDAP server
while the role still exists. The role should be able to be deleted
and not get a 404 Not Found.

(The description mentioned users, but this also applies to groups.)

The server is changed so that it doesn't check for the existence
of the user or group.

Documentation on how-to develop Keystone Extensions

This file documents in details how to develop an
extension following the Keystone guidelines.
It also improves the already existing `example` extension
adding some boilerplate code.

Remove obsolete driver test module

Now that all drivers use the abc module to create abstract
base classes, there is no need to test that they raise
NotImplemented by default.
