On persistent connections with federation debug flag.

The dbd may need to send informaion back right after it registers
(e.g. federation state).

The update could be from a controller registering which wouldn't have
the fed_name set yet.

This reverts commit b7dc369a7fea7caf18ed3515b77f68395056eb99.

rpc_version -> protocol_version

e.g.
sacctmgr modify federation <fed> set clusters=

ex.
sacctmgr add cluster <cluster(s)> federation=<fed_name>
sacctmgr modify cluster <cluster(s)> federation=<fed_name>
sacctmgr add federation clusters=<federation_names>

Goes on the cluster instead.

allocated and then filled in instead of sending in an already
allocation structure.
