Restructure code for libp2p upgrade (#3850)

Browse Source 
Our custom RPC implementation is lagging from the libp2p v50 version. 

We are going to need to change a bunch of function names and would be nice to have consistent ordering of function names inside the handlers. 

This is a precursor to the libp2p upgrade to minimize merge conflicts in function ordering.
