Set a default HazelcastInstance after init() is called, and use this instance in getLock() to acquire a lock in the cluster.

no need to cast docInfo entries to String -- they are all strings

set revision history, the create/update dates and the owner/submitter (correctly)

use shared method for looking up "docInfo" map -- both in Metacat replication and in D1 system metadata generation

make default formatting a little bit easier to read

reformat code -- no changes

refactor SystemMetadata creation into separate class from the MetacatHandler -- this will be shared by upgrade code and normal metacat api.

include all document revisions when generating "missing" system metadata
