Metacat

check reservation before create/update

Use D1 properties to set node values, and add the 'WAR VERSION' back into the node name for deployments.

add hasReservation() method (NotImplemented, however)

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

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
