Add parameters to Redis initialization.

Still searching for confirmation that username and password are the
parameters to be submitted to Redis.  Issue #7.
Merge branch 'master' into issues/7
Remove incorrect username parameter from redis.

The redis database doesn't use a username for a connection.  It only
uses a password for authorization.

This should solve issue #7 but this still needs to be reviewed and
tested before merged into master.

Add check for Vagrantfile to generated setUp.

The generated tests' setUp now includes a check for a Vagrantfile
(similar to vagrant's check) which will skip the test if it's not found.

This check is contained in a helper function added in this commit as
well.  find_vagrant_file will search the current directory and its
parents for a Vagrantfile.
