core: core.Lattice supports config change (#276)

Besides making core.Lattice supports config change,
This PR also include the first test for below scenario:
- Configuration changes are registered before test
   running
- Those changes are carried/broadcasted as payload
   of blocks
- Only one node would initiate these changes, however,
   all nodes would finally receive/apply those changes
   to their own test.Governance instance.
