test: add unit test for redis driver

[danielroe]

Following #163, this enables unit testing with redis. We can then update the testDriver utility in that PR to add a regression test for the bug it is fixing.

He @danielroe,
I already added tests, including different authentication methods to #160. They are not using a mock, but instead a in-memory actual redis implementation like the in-memory mongodb one in the mongodb driver.

Rats, how did I not see this?! That sounds better. I'll check later on.
