Subject: test: make StateChangeRequest broadcast-able (#305)

Make `test.StateChangeRequest` behaves like tx
on ethereum:
- Can be broadcasted and cached in a pool.
- Uniquely indexed, and be removed after
  applied.

Changes:
- Make cloneDKGx functions in test.State as
  utilities.
- Add hash and timestamp fields to
  test.StateChangeRequest.
- Add two methods to test.State:
   - PackOwnRequests would pack all pending
     change requests owned by this instance as
     byte slice, and move them to global pending
     requests pool.
   - AddRequestsFromOthers would add pending
     change requests from others to global
     pending requests pool.
- The method State.PackRequests now would pack
  requests in global pending requests pool.
- The method State.Apply would remove
  corresponding StateChangeRequest by hash.
