python-manilaclient/manilaclient/tests/unit/test_client.py
Goutham Pacha Ravi 2d4df937d5 Use unittest.mock instead of third party lib
mock was adopted into standard python
in version 3.3 [1]. Since python-manilaclient
no longer supports python2.7, we can use the inbuilt
mock package rather than the third party
lib.

Also fix some issues with imports that
weren't following our import conventions
of grouping imports [3]
