Refactor pre protocol execution

[JesseAbram]

Refactor pre protocol execution steps that use similar code into reusable functions.

This is setting up the websocket connections functions like:

• do-dkg
• do_proactive_refresh

[HCastano]

What do you mean by "pre protocol execution"? For the functions you mentioned, can you link the relevant places in the codebase?

[JesseAbram]

so in do_dkg, do_proactive_refresh and do_signing each require setting up a WS connection logic like open_protocal connection, getting the channels and a few others are copy pasted across these functions and can be generalized

[ameba23]

For more context, crypto/protocol/src/execute_protocol.rs has 3 functions mentioned above which all share a large amount of repeated code making them hard to maintain.

We could fix this either with a trait and generics or separating stuff in to common sub-functions.

I think @JesseAbram said that @fjarri has some ideas about how best to do this.

I could take on doing this once im done with wasm problems as im currently looking at these functions quite a bit.
