Fix apt-get install, tests fixes

check_redis should use shell not command

the redis_cli check was silently failing - it reported an error
that the | argument was invalid, but it returned a 0 exit code
anyway. You cannot use pipes | or other bash constructs using
the command module, you must use the shell module.

use tox-lsr version 2.5.1

This version removes support for molecule until we can figure out
what to do about molecule. This should make all of the tox tests
pass (except for python 2.6).
