* Add passlib to RHEL test instance
This looks like the only tests instance that is missing this libary. It is needed for vars_prompt tests.
* Create setup roles for pexect and passlib
Switch to using aliases rather than installing directly in the test scripts
* Fix all cases with pause and ctrl+c
- naked:
- pause:
- with prompt
- pause: prompt=hi
- time wait
- pause: seconds=60
- time wait with prompt
- pause: seconds=60 prompt=hi
