Clark Boylan 320dbd639a Check for new Gerrit on disk caches when upgrading Gerrit
Update the Gerrit upgrade job to check for new on disk h2 cache files.
We discovered well after the fact that Gerrit 3.5 added new (large)
cache files to disk that would've been good to be aware of prior to the
upgrade. This change will check for new files and produce a message if
they exist.

# Note this playbook is in the zuul/ dir because it is very test specific
# currently. We could potentially rewrite things so that this can be used
# in production but it isn't currently ready for that.
#
# In particular it bootstraps users and test changes assuming a test env.
