rCOMMe7885e5a97fa: [services][identity] wallet login

Summary

Full implementation of wallet login. Steps:

Parse SIWE message and signature from request
Verify message using siwe-rs crate
If verification is successful, generate a token, store it in the token table in DynamoDB, and then return it to the caller

Note that PAKE login is not covered here. It will be in a separate diff.

Test Plan

Successfully signed in with a metamask wallet

changed the type of token in the .proto file to string, so this is the corresponding code change

services/identity/src/service.rs
71 ↗	(On Diff #13549)	Error case isn't handled
72 ↗	(On Diff #13549)	When would this be None?
73 ↗	(On Diff #13549)	This is really hard to read, please refactor. The error handling in the match arms is heavily duplicated. For starters, make a subroutine that returns a Result, and in here do the `if let Err(err) = result { log and break }` thing once.

This revision now requires changes to proceed.Jun 17 2022, 11:53 AM

create a subroutine to improve error handling

handle unhandled error case and unhandled option case

services/identity/src/service.rs
72 ↗	(On Diff #13549)	`oneof` fields are completely optional, which is why this can be `None`. we are reconsidering the use of `oneof` across all our .proto files, but i've handled the `None` case in the latest revision.

services/identity/src/service.rs
62 ↗	(On Diff #13732)	What is the purpose of it?
87–105 ↗	(On Diff #13732)	I think you can create a function that contains the repeated logic

services/identity/src/service.rs
62 ↗	(On Diff #13732)	`MyIdentityService` doesn't implement `Debug`, so we have to skip `self` when we do tracing
