[Interop] Improve RPC Codebase + Start Beacon Chain With Mock ETH1 Values (#3407)
* add main.go

* interop readme

* proper visibility

* standardize and abstract into simpler funcs

* formatting

* no os pkg

* add test

* no panics anywhere, properly and nicely handle errors

* proper comments

* fix broken test

* readme

* comment

* recommend ssz

* install

* tool now works

* README

* build

* readme

* 64 validators

* rem print

* register the no powchain flag

* work on mock eth1 start

* common interface

* getting closer with the interface defs

* only two uses of powchain

* remove powchain dependency

* remove powchain dependency

* common powchain interface

* proper comment in case of flag

* proper args into rpc services

* rename fields

* pass in mock flag into RPC

* conforms to iface

* use client instead of block fetcher iface

* broken tests

* block fetcher

* finalized

* resolved broken build

* fix build

* comment

* fix tests

* tests pass

* resolved confs

* took them out

* rename into smaller interfaces

* resolve some confs

* ensure tests pass

* properly utilize mock instead of localized mock

* res lint

* lint

* finish test for mock eth1data

* run gazelle

* include flag again

* fix broken build

* disable powchain

* dont dial eth1 nodes

* reenable pow

* use smaller interfaces, standardize naming

* abstract mock into its own package

* faulty mock lint

* fix stutter in lint

* rpc tests all passing

* use mocks for operations

* no more mocks in the entire rpc package

* no  mock

* viz

* testonly
