SSL Error with st2 sensor connection redis

[cshelke52889]

Getting these errors while connecting to redis with SSL. A normal action runs fine, sensor seems to be having problem. I did try to use the fixes mentioned in eventlet/eventlet#371 but none of the different combinations of library versions seem to work for my case.

lib versions tried:
redis==latest/3.3.5
eventlet==latest/0.17.4
Flask-SocketIO==4.2.1
dnspython==latest/1.16.0

You can accomplish the same use case with a rule using the cron trigger as you can with a polling sensor. I recommend refactoring into an action - rule if possible.
