Add v3 RPC for sending cluster states to content nodes

Supports sending states for multiple bucket spaces at once, with
possibilities for extending protocol later for sending distribution
config etc. Payload is LZ4-compressed when possible.

If a receiver node does not understand the v3 protocol, the protocol
version is transparently downgraded to legacy v2 RPC.
