Bug 1038317 - Use of remote client API results in error/warning messages regarding indirectly referenced JPA annotations not being resolvable

Added Hibernate Core (for CascadeType enum) and Hibernate JPA Annotations to the CLI distribution

Tested with the wiki remote API example https://docs.jboss.org/author/display/RHQ/Java+Client+Sample+Class
(Only 1 warning remains at compilation, because the sample class uses a deprecated method from the Remote API)
[BZ 1069547] Fix AS7 plugin itests.

The itests run with EAP 6.1.1 that does not support patching so I
added an exception to the rule of non-null metrics in the itest.

[BZ 1114199] fix handling of late data

My previous commits that involved setting the column timestamp on inserts had
to be reverted. When aggregating late data, it is possible to end up with a
clock tie (See https://wiki.apache.org/cassandra/FAQ#clocktie for details). In
those situations the columns might not get overwritten.

The key thing is to ensure that we do not try to recompute aggregate metrics
when some or all of the source data has already expired, leading to new,
incorrect data. I have put changes in place that should prevent this from
happening.

This commit also includes a change to IndexIterator. It will now continue
loading pages if there is a read timeout. Previously, the exception would go
uncaught causing data aggregation to abort early.
