Client state filtering

[adizere]

Crate

Summary

Add support in Hermes for filtering based on client state threshold. Concretely, with such a filtering feature, Hermes should undertake no activity on a client, connection or channel if the client on any end has a trust threshold different than a predefined allowed one.

Initially, we'll parametrize Hermes with a threshold of numerator == 1 && denominator == 3.
Hermes will ignore any activity involving a client that has a trust threshold different than this.
