Patch implementing ideas above. Please review.
There are few points in particular where more discussion is needed:
# Introduced a new interface {{SharedDataStore}} which all supporting data
stores would implement if they support the shared access. Should this interface
be in jackrabbit as {{S3DataStore}} may also need to implement this? Currently,
I have it as part of Oak so thats its easier to review.
# The only implementation currently is in {{OakFileDataStore}}. Is this ok or
should be moved to the {{FileDataStore}}?
# The current implementation for a unique cluster {{repositoryId}} keeps it as
a property {{:clusterId}} in a new node {{/:clusterConfig}}. This information
is registered in the node/data stores in the {{*NodeStoreService}}. The
{{repositoryId}} is used to register different clusters in the DataStore as
well as identify the references from the cluster that are kept at the root of
the DataStore.
