Use keystone uuid tokens to optimize test run time

This commit does the following:
  - Overrides KEYSTONE_TOKEN_FORMAT to uuid in ``local_conf``
    sections of patrole.yaml because Patrole can be optimized
    to run faster in the gates using uuid tokens instead of
    fernet tokens [0][1]
  - Increases overall gate runtimes to 130 from 70, because
    while we want our jobs to run within 1 hour, occassionally
    our jobs fail prematurely due to limited resources, which
    only results in needless rechecking of jobs
