simulation: use test.Governacne in simulation (#311)

* Move simulation.Network to test package
* Use test.Governance in simulation
* Pack/Apply state request in blocks payload
* Add Governance.SwitchToRemoteMode

This would trigger governance to broadcast
pending state change requests when changes.

* Allow to marshal/unmarshal packedStateChanges
* Attach test.Network and test.State
