Contract owner entity does exist anymore. Contract migration
now managed by side chain committee which are Alphabet nodes of
the Inner Ring.

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

With `NetmapCandidate` storage nodes can monitor
if they are expected to be in the netmap at next
epoch or not. This is also important for monitoring
when some nodes does not bootstrap immediately.

There is a number of contracts which return only `true` value.
Also handling `FAULT` on the client is easier then also checking return
value.

For committee operations in side chain we can't use 5\7 multi
address, instead we should use 4\7 for this case.

This check was useful when there was a single
entry point in contract. But right now there is
no point in this.

Define IRNode structure in common package. Replace innerRingInvoker function
in common package and export it. Reuse this function in all contracts.

Replace vote/remoteVotes functions from all contracts (except alphabet) to
common package. Additionally replace setSerialized and bytesEqual. Create
InitVote function and use it in NeoFS and Netmap contracts.

Create common package. Define Ballot struct in common package. Use new type
in all contracts with ballots.

Remove old ballots first so there won't be any
interference with votes of the same tx in the
future after `blockDiff` blocks.

There are cases when NeoFS applications need to fetch netmap
snapshot of exact epoch. This method provides convenient atomic
way to do that.
