Feature: Ban makers in configuration

[3nprob]

Motivation

As a measure to misbehaving makers, allow banning makers in configuration. This can be useful for example when the same maker continuously picked and timing out.

Suggestion

Add new configuration:

[POLICY]
banned_maker_ids=J5ABC1,J5DEF2,...
banned_maker_bonds=deadbeef:0,abcdef:1,...

Banning by banned_maker_ids will not be effective. Banning by banned_maker_bonds will be much better.
