handle timed replication of system metadata. there are still a few outstanding issues:
-track server location of system metadata-only entries
-replication policy flag for system metadata-only entries?
-locking for replicated entries?
-forced replication of entries

-remove system metadata guid -> local id mapping (there is no document for system metadata now)
-include system metadata elements when replicating data objects (TODO: transfer all system metadata structures with the docinfo request).
TODO: remove docid+rev from the systemMetadata table definition

Commenting out these MetacatRestClient tests because the Metacat RestService is no longer registered as a servlet and needs to be removed, along with the associated MetacatRestClient and tests.

Fixed MetaCatServletTest test failures by removing the hardcoded username/passwords used in the tests and replacing those with data from metacat.properties.

Fix AuthLdapTest to use accounts that are more reliable when searching for existing accounts in the getPrincipals output.

removed newline addition to test doc now that the newline problem is fixed in utilities project. Small adjustments to comments and debug statements to aid in debugging. Reordered tests to remove possible insertion between read and getLastDocid test.

Make this class be the subclass of the MCTestCase. The super class will initialize the property service for it.
