Gerrit made new releases and we should update to them. Release notes can
be found here:
https://www.gerritcodereview.com/3.5.html#354https://www.gerritcodereview.com/3.6.html#363
The main improvement for us is likely to be the copy approvals
performance boosts and error handling. We still need to run that prior
to our 3.6 upgrade.
Note we currently only run 3.5 in production but we test the 3.6 upgrade
from our current production version so it makes sense to update the 3.6
image as well.
