Chuck Short fbbd58a459 Remove mox3 completely
The porting of mock is complete. This fullfills the
community goal
200~"Remove Use of mox/mox3 for Testing" set for Rocky:
https://governance.openstack.org/tc/goals/rocky/mox_removal.html

This commit does the following code:
- Remove dead code that was previously used by mox.
- Raise the requirement to the Rocky M2 relase of Horizon.
- Convert the clients to use mock.
