Metacat

removing unneeded class (never used)

cleaned up mock tests on hzObjectPathMap. split out code for mocking a datastore into MockObjectPathMap.

initialize Hazelcast from the custom configuration when initializing the Metacat service.

handle entryAdded and entryUpdated the same - update the entry if it exists, otherwise create it

handle entryAdded (to hzSystemMetadata) to store sysmeta to local store when it is not already present

make isScienceMetadata() method public/static to be called throughout Metacat

only create ObjectFormatId when we actually have the parameter (downstream we rely on it being null or not when constructing the query)

add code to handle new entry when it is not on the local member of the sysmeta cluster

clean up imports - randome quicktime package had been included

comment out processCluster connections that use hzClient until that is finalized
