[EPOCH TRANSITION] - Membership trait has an additional method to fetch a stake table for a given epoch

[lukaszrzasik]

What is this task and why do we need to work on it?

This is required to implement a variable stake table. Stake table can change while transitioning from one epoch to the next. Looking at it from a different angle: there are multiple stake tables, one per epoch.

We need an additional method that fetches a new stake table for the given epoch. This method should be stubbed in HotShot. The real stake table is to be fetched from a contract in L1. This issue should have a corresponding issue in sequencer project in which the method is implemented.
