The mock third party library was needed for mock support in py2 runtimes. Since we now only support py36 and later, we can use the standard lib unittest.mock module instead. Note that https://github.com/openstack/charms.openstack is used during tests and he need `mock`, unfortunatelly it doesn't declare `mock` in its requirements so it retrieve mock from other charm project (cross dependency). So we depend on charms.openstack first and when Ib1ed5b598a52375e29e247db9ab4786df5b6d142 will be merged then CI will pass without errors. Depends-On: Ib1ed5b598a52375e29e247db9ab4786df5b6d142 Change-Id: I8757d430ab233f4a21d1d599f1a7a9a0dc68d7ef
