Neo Legacy used migration mechanism to update contracts.
N3 provides update method in native management contract.
Therefore, it makes sense to rename `Migrate` to `Update`.

As soon as migration required changes in memory, we

which is unpleasant and annoying.

Proxy contract used by notary contract as a main tx
payment provider. `Verify` function verifies if
main tx contains multisig of 5\7 inner ring
nodes. If so, then contract pays for transaction.
This is easier than support multisig wallet with
GAS assets, because inner ring can change, therefore
multisig wallet can change periodically.
