* Dropped block should not be added to db
- Here "dropped" means a block is older than
current tip of that chain.
* "Acking blocks doesn't exist" should be treated
as an error when adding a block

This info is required when application layer needs
to do something related to the underlying DAG, not
just compaction chain.

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.

* remove sanity check when adding blocks.
* call VerifyBlock after lattice's sanity check.
* remove checkRelation flag.

* Replace "log.*" with logger.
* Add simple logger to log with log package.
* Add debug logs to all calls to these interfaces:
- core.Application
- core.Governance
- core.Network
* Add Stringer to these types:
- types.DKGComplaint
- types.AgreementResult
- types.DKGMasterPublicKey
- types.DKGFinalize

* Refine the initial value for empty time slot.
* Fix DATA RACE
netowrkConnection is reset for each test,
however, our Consensus instance is not
stopped after one test is finished, they
might continue use network interface for
a while.

* Add test for num of chains changes.
* Return error in latticeData.prepareBlock
* Compare two positions
* Modify chainStatus from height-based to index-based.
* Fix consensus to use round variable
* Remove sanity check in chainStatus
* Fixup: refine sanity check
- verify if round switching is required or not by
chainTip's config.
- make the logic in sanity check more clear
- pospone acking relationship checking, they
are more expensive to check.

* Extract types.FinalizationResult
* Change interface:
- Application.BlockConfirmed returns whole block.
- Application.BlockDelivered returns partial result.

* Make sure block pool is large enough
It's safe to use a larger blockPool when
the number of chains is smaller.
* Construct latticeData via config.
* Seek acked blocks in blockdb when
unable to find them in memory cache.
In previous implementation, we assume
our cache in memory is enough to perform
DAG's sanity check. However, it's no longer
true when the number of chains might be
changed between rounds.
* Simplify purge.
Remove the relation to purge block by chainStatus.

* Refine core.Governance interface
- Remove types.NodeID from interface declaration.
- All parameter should be round based.
* Add core.NodeSetCache
* Agreement accepts map of nodeID directly.
* test.Transport.Peers method return public keys.

1) Remove RoundHeight from config.
2) NotarySet is not from governance contract, we get Node set intead.
Notary set is caculated from the NodeSet using CRS.
3) CRS is not in the governance interface.

- Move key-holder to authenticator
Make core.keyHolder public as core.Authenticator, it
is not required to make this part an interface.
- Make private when there is no need to go public.
- Fix data race

* Split interface
* Rename nonblocking-application to nonblocking
Parts needs nonblocking gets more.
* Implement core.nonBlocking based on interface split
* Fix: the witness parent hash could be parent on compaction chain.
* Rename Application.DeliverBlock to BlockDeliver
To sync with naming of other methods.
* Change methods' fingerprint
- BlockConfirmed provides block hash only.
- BlockDeliver provde a whole block.

A shard is basically DEXON v1 components,
except the strongly acked part, including:
- maintaining lattice structure
- total ordering
- generate consensus timestamp
