Support optional minerID in K2 PoW input (#4678)
Browse files Browse the repository at this point in the history 
## Motivation
Closes #4656 

## Changes
Adds an optional minerID that created the k2 pow (_k2 pow creator id_) to post proving and verifying.

## Reasoning for making it optional
In order to be able to test in on a real network (devnet-401) pre-genesis. For genesis we will set `post-minerid-in-k2-pow-since-epoch = 0` and later remove the config field along with branches in code.

## Test Plan
- existing UTs
- systests
- devnet-401 (set `post-minerid-in-k2-pow-since-epoch` to the epoch near in the future)
