Remove logic of allowed methods list from object, container and account
servers. Instead of it add replicator decorator to utils and use new
decorator for REPLICATE methods in object/account/container servers.
This decorator mark method as special for usfor use only by the
replication.
If the option replication_server is not used, then this mechanism is not
enabled. If the replicaton_server option is set (not None) then the
respective server is a replicator (option value is True) and should use
ONLY the methods marked for replication server using the decorator, or
it is a normal server type and should NOT use methods marked for the
replication server.
