spring-cloudGH-373: Re-enable aggregator tests (spring-cloud#377)

Fixes spring-cloud#373

The fix in Spring Integration has made it into the latest SNAPSHOT.
See more info in the linked issue

* Update to the latest Testcontainers: it does not require credential for pull command any more
* Remove obsolete `MessageStoreType.GEMFIRE`
* Add `<doclint>syntax</doclint>` to ignore missed javadocs on public methods
