feat: add support for different fees per dest domain to basic/percentage fee handler

[nmlinaric]

Description

This introduces a mapping for fees per destination domain. Now we don't have to deploy a new handler for every fee amount, they all can be setup in a single basic/percentage fee handler.

Also removes setting up fees in migrations since now there would be too many moving parts to do it automatically.
In general we need to rethink about fees and how to approach to migrations.
