Make Validator Set Network a first-class property

Browse Source 
There already should only be one validator set operating per network. This
formalizes that. Then, validator sets used to be able to operate over multiple
networks. That is no longer possible.

This formalization increases validator set flexibility while also allowing the
ability to formalize the definiton of tokens (which is necessary to define a
gas asset).

Validator Sets are defined at the protocol level, with the following parameters:
- `bond` (Amount): Amount of bond per key-share.
- `coins` (Vec\<Coin>): List of coins within this set.
- `participants` (Vec\<Coin>): List of participants within this set.
- `bond` (Amount): Amount of bond per key-share.
- `network` (Network): The network this validator set operates
over.
- `participants` (Vec\<SeraiAddress>): List of participants within this set.
Validator Sets are referred to by `ValidatorSetIndex` yet have their data
accessible via `ValidatorSetInstance`.
Validator Sets are referred to by `NetworkId` yet have their data accessible via
`ValidatorSetInstance`.
At launch, there will solely be Validator Set 0, managing Bitcoin, Ether, DAI,
and Monero.
### Participation in consensus
### Participation in the BFT process
All Validator Sets participate in the BFT process described under
[Consensus](./Consensus.md). Specifically, a block containing In Instructions
for a coin must be approved by the BFT majority of the Validator Set responsible
for it, along with the BFT majority of the network by bond.
At this time, In Instructions for a coin are only expected to be included when a
validator from the Validator Set managing the coin is the producer of the block
in question.
Since there is currently only one Validator Set, the aforementioned BFT
conditions collapse to simply the BFT majority by bond. Ensuring BFT majority
per responsible Validator Set is accordingly unimplemented for now.
All Validator Sets participate in consensus. In the future, a dedicated group
to order Serai is planned.
