Gerrit made new bugfix releases for the two images we're currently
building. The most important one is for 3.10.4 as we're currently
deploying 3.10 in production. The full changelog for 3.10.4 is here:
https://www.gerritcodereview.com/3.10.html
No breaking changes are noted. Primarily a bugfix release.
Bundling this update with a change to increase h2 compaction time may be
a good idea.
