MODE-1765 - Updated the AS7 distributions so that there's a dedicated one for integration-testing (which overrides the default one). The default AS7 distribution has been "cleaned up" and is now testing only during the "assembly" phase via a separate Maven module.
MODE-1760 Add explicit dependency for jboss-connector-api_1.6_spec
MODE-1760 Rearranged JCA dependencies
MODE-1772 Added test case to replicate the problem of creating nodes under projections
MODE-1772 Ignored replication test case

This is to be un-ignored when fixing the issue.
MODE-1770 Added PESSIMISTIC locking to the default, in-memory Infinispan configuration

The LocalEnvironment class and its createDefaultConfiguration() method
are used to create the default cache configurations for in-memory content.
This method does set up the transactional behavior, but does not set
the locking. Therefore, I think it is prudent to add code to this
method that sets up the LockingMode of PESSIMISTIC.

Verified that this has no negative effect on the tests.
MODE-1775 Improved the Session.getNodeByIdentifier() method

Improved the method used to look up nodes by string identifier. The
logic is now:

- If the identifier is a full node key, use it to look up the node
with that key; if not found, continue
- Look for the node in the workspace content, using a key that is
the same as the root node key except with the supplied identifier part;
if not found, continue
- Look for the node in the system workspace content, using a key
that is the same as the "/jcr:system" node except with the supplied
identifier part; if not found, throw the ItemNotFoundException from
step #2.

The method previously just did steps 1 and 2, so step 3 is what was
added. A new test case verifies that the change fixes the original
problem
MODE-1772 - Updated the connector SPI and the document store so that a writable connector can generate its own ids when new nodes are created.
Added overlays folder to .gitignore.
MODE-1774 Changed the problematic error log message to debug

Also changed the verbage to not sound so dire, since the repository
might not yet have been started.
MODE-1561 - Added the writeLimit parameter to the TikaTextExtractor.
