Update ssl-ha molecule scenario testing

[dann1]

passenger-ha molecule scenario was renamed to ssl-ha after #101. features.passenger was tested on this scenario. Since passenger is not required by FireEdge, it has been dropped and no longer tested. one-deploy <=1.2.0 provided ssl features as well, but they were never tested on molecule.

The purpose of this issue is to update the ssl-ha molecule scenario to verify reverse proxying with ssl termination using both apache and nginx. ssl certificate generation is required.
