Metacat

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

add test for synchronization failed -- TODO: verify that the log record made it in the logs

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

include test for replicate() method -- still fails as not implemented

allow null objects (use default checksum)

wire-up the getCapabilities() and getOperationStatistics() methods for when they are actually implemented (tests fail now)

test listObjects()

include MNAuthorization tests

refactor to use common superclass D1NodeServiceTest for shared methods
