Merge branch 'stable-3.5' into stable-3.6

* stable-3.5:
  Remove dependency on //java/com/google/gerrit/proto
  Restore dockerized integration tests
  Adapt Bazel build and deps to latest stable-3.5
  Adapt to the latest Index interface in stable-3.5

Since Ia64a599440 TimestampRangePredicate is migrated to use Instant
instead of obsolete Date class. Adapt the ElasticQueryBuilder for this
migration.

ElasticV7QueryChangesTest overrides byTopic() method to adjust to ES
behaviour for "prefixtopic" predicate. "prefixtopic" predicate was added
in release 3.6 and that's why this is done in the merge commit.
