generalize exception handling -- add cause detail

Changes to setReplicationStatus and isNodeAuthorized(), working out minor bugs in replication.

include exception cause when throwing new exception (combine RuntimeException in Exception handling -- they are almst identical)

throw InvalidToken when session is null

correct typo

Send the correct node id (the target node) when calling setReplicationStatus()

get pid from normal params, not the URL -- the client should include them in the params -- and not as a serialized "object" since it is just a string value

check obsoletes and obsoletedBy PIDs when updating objects

delete system metadata when MN.delete() is called.

throw InvalidToken when there is no session (certificate) provided in update() and delete() methods.
