Metacat

add hasReservation() method (NotImplemented, however)

use objectFormatIdentifier for listObjects()
remove provisional system metadata indicator - Metacat will not implement reserveIdentifier()

use correct log name for the class

consistently construct username/groups for MetacatHandler calls - also consistently call isAuthorized

provisional replicate() implementation -- does not check if the session's subject is "allowed" to do this.
the test also requires 2 servers -- right now it attempts to replicate with itself which will fail because of duplicate IDs

provisional version of getOperationStatistics() -- not clear if we are meant to aggregate by hour or by day

provisional getCapabilities() implementation. Much of the synchronization information and node health is omitted.

simplify the get() method -- no need to use temp files for this operation

implement d1 paging for the log record results

Reverting the resultset order in querySystemMetadata(). Thanks Ben.
