Mark more tests as flaky

This adds the necessary annotation to repeat flaky tests if necessary
for tests described in these issues:
* JanusGraph#1457
* JanusGraph#1459
* JanusGraph#1462
* JanusGraph#1464
* JanusGraph#1465
* JanusGraph#1497
* JanusGraph#1498
* JanusGraph#2272
* JanusGraph#3142
* JanusGraph#3356
* JanusGraph#3392
* JanusGraph#3393
* JanusGraph#3651
* JanusGraph#3931
* JanusGraph#3959
* JanusGraph#3960

I went through the recent builds on `master` and checked all failed
builds. I think this should handle all flaky tests that occurred in
these builds, apart from the TinkerPop test where I just don't know how
to deal with it: JanusGraph#3841, but we can of course just address that in
another PR.
We however also sometimes get failed jobs because of some intermediate
issues where a backend cannot be properly set up or teared down for some
reason or downloading some artifact just fails. I don't know what we can
do to improve this, but I would also consider that out of scope of this
PR where I just wanted to deal with failing jobs due to specific tests
being flaky.

Hopefully, this will already lead to significantly fewer cases where we
have to manually restart failed jobs (which I had to do a lot lately for
all these Dependabot PRs).
