Redis cache tests passed

Failing ones are the older RRIO tests with HTTP (although enrichment tests for HTTP are passing) due to a problem with urllib3. I'll check.

[riteshghorse]

This passed

And I think found the problem with other RRIO test as well :)

Thank you both Danny and Valentyn for your reviews!

Thanks @tvalentyn! Made changes from some of your suggestions but kept a few of them as is. If this looks good I'll drop the postcommit file once tests pass and merge. Thanks!

I'm removing this test

Since this failure is not reproducible locally and fails with a different error everytime - it was throwing this earlier

and we already have 3 other tests passing for testing the RRIO with MockAPI.

@tvalentyn I ended up using the @property for setters. Thanks again for the suggestions!

All tests passed. Dropping the postcommit file
