Subject: Bug 244124 - Add Nested FetchGroup

Checked into trunk.
Main patch.

The patch provides basic nested fetch group functionality.

FetchGroup got a new shouldLoad flag - it indicates whether its attributes
should be loaded.
Also there is a new class LoadGroup, which allows to manage loading of
individual relational attributes.

There is still work to be done in the area of merging with cache and fetch

A new test package org.eclipse.persistence.testing.tests.jpa.fetchgroups was

See simple examples of different loading arrangements in findMinEmployee tests
in NestedDefaultFetchGroupTests.

A simple merge was tested and works:
serialize object with a fetch group applied to it;
update serialized object (even attribute outside the fetch group);
serialize it back to the server;
See a simple example in SimpleSerializeFetchGroupTests.simpleSerializeAndMerge.
