Create the new Collation RLP object

See original GitHub issue

What is wrong?

(Updated the issue, separated this ticket from VMC contract)

`CollationHeader`

2018-04-14 updated:

shard_id           uint256 // pointer to shard
chunks_root        bytes32 // pointer to collation body
period             uint256 // timestamp
proposer_address   address

`Collation`

header    CollationHeader
body      CollationBody

How can it be fixed

Since there are two other issues are related to VMC, it might be better to create a new Collation class to avoiding influencing VMC.

@mhchia

Some fields renamings are still in discussion.
Removing state_root from Collation may make some tests fail due to this line: https://github.com/ethereum/py-evm/blob/3784a87d0850c92d5865d97ce4bb6f5075d47896/evm/vm/forks/sharding/vm_state.py#L45 Which means we may have to make another temporary NewCollation class or decouple state execution.

I suggest something you can do before this issue:

Move VMC out of evm/vm because (1) it’s not part of VM and (2) it helps for decoupling state execution and other processes.
Ping @pipermerriam , what do you think of that we move VMC contract to ethereum/sharding repository and we make sharding repository to be a submodule of py-evm? If it’s okay, @mhchia would you help to move?
Write down basic VMC API doc. (don’t need to be perfect)
