Revert "Set tripleo ci control variables based on job name"

This reverts commit 9fdca6e28a435012d1be354d8547ec74f2338b16.

Changing behavior based on JOB_NAME is extremely unsafe and
should not be done.  Instead, set variables in the JJB
templates in config that describe what the job should do, and
then in this repo, enable settings accordingly.
