* [slash] Factor out common for validator, stub out slash application, finish out deserialization setup

* [slash] Factor out data structure creation because of var lexical scoping

* [slash] Seem to have pipeline of unit test e2e executing

* [slash] Add expected snitch, slash amounts

* [slash] Checkpoint

* [slash] Unit test correctly checks case of validator own stake which could drop below 1 ONE in slashing

* [config] add double-sign testnet config (#1)
