ADD: Ban removes node from consensus

Current

Banning a node only removes them from TSS, they remain in consensus and can slow down a network upgrade

Desired

Banning a node also removes them from the consensus set, allowing the network to upgrade faster in emergencies.

A banned node does not suffer any penalties, but they must leave the network, destroy their node, then set it back up before coming back in, since their node address is permanently jailed.
