DCP connections with long names break the STATS "dcp" command. (See MB-34280). Java-DCP-client should generate names that are no longer than the memcached limit.
Memcached should disallow DCP connections with names greater than 200 characters (was: ns_server connections may be terminated if a client uses a long DCP_OPEN.name)
Rebalance fails because DCP connection name is too long
