Metacat

check if system metadata exists rather than just the id mapping (before creating the entry)

treat access rules atomically - do not group them together otherwise the intent is subverted

only "save" to the shared system metadata map - not directly to the table store.

do not send <systemMetadata> with the <docInfo> replication information - this is handled by the Hazelcast shared map

rely on Hazelcast to store the SystemMetadata locally for the node. Entry event listeners store the shared system metadata on their local node when alerted. TODO: remove old replication code that included system metadata xml when replicating scimeta and data

move bulk of the Hazelcast code into HazelcastService from CNodeService so that it is centrall located - easier to manage and configure

verify that the sysmeta checksum value matches the computed checksum value when calling create()
https://redmine.dataone.org/issues/1795

include sysmeta for uploaded BIN data that comes through the legacy Metacat servlet API

check for null pointers when adding system metadata/creating records during cn.create()

removing unneeded class (never used)
