Add support for Elasticsearch 6.4.0

According to the release notes [1] there are several breaking changes,
but none of them seem to affect Gerrit's integration.

Update the version manager and adapter to recognize 6.4.* as a supported
version, and modify the test container to use 6.4.0 for the V6 tests.

Update the reindex and ssh index tests to also test against 6.4.0.
