* BlockId removal: refactor of runtime API - tests

- tests adjusted to new runtime API,
- some tests migrated from block number to block hash

* benchmarking-cli: BlockId(0) migrated to info().genesis_hash

`runtime_api.call()` now requires the block hash instead of BlockId::Number.
To access the genesis hash widely used in benchmarking engine the Client
was constrained to satisfy `sp_blockchain::HeaderBackend<Block>` trait
which provides `info().genesis_hash`.

* trivial: api.call(BlockId) -> api.call(Hash)

For on-demand justifications, peer selection is based on witnessed
gossip votes. This commit changes the condition for selecting a peer
to request justification for `block` from
"last voted on >= `block`" to "peer last voted on strict > `block`".

When allowing `>=` we see nodes continuously spamming unsuccessful
on-demand requests to nodes which are still voting on a block without
having a justification available.

One way to fix the spam would be to add some rate-limiting or backoff
period when requesting justifications.

The other solution (present in this commit) is to simply request
justifications from peers that are voting on future blocks so we know
they're _guaranteed_ to have the wanted mandatory justification
available to send back.

* sc-network-test::Peer: block push methods return hashes vec

This commit reworks the block generation/push methods in
sc-network-test::Peer.

Now methods are providing the vector of hashes that were built.

This allows to get rid of redundant `block_hash_from_id` call, as all
hashes are known just after being built.

Similar approach was taken in BeefyTestNet::generate_blocks_and_sync
method.

* client/beefy: fix on-demand justif sync for old blocks

When receiving BEEFY justifications for old blocks the state might
be pruned for them, in which case justification verification fails
because BEEFY validator set cannot be retrieved from runtime state.

Fix this by having the voter give the validator set to the
`OnDemandJustificationsEngine` as request information. On receiving
a BEEFY justification for requested block, the provided validator
set will be used to validate the justification.

Network events are many and very frequent, remove the net-event-stream

* client/beefy: prepare worker for persisting state

* client/beefy: persist voter state

* client/beefy: initialize persistent state

* client/beefy: try to vote from the very beginning

Now that voter is initialized from persistent state, it makes
sense that it can attempt voting right away. This also helps
the genesis case when we consider block `One` as mandatory.

* client/beefy: add tests for voter state db
* client/beefy: persist voter state as soon as initialized
* client/beefy: make sure min-block-delta is at least 1
* client/beefy: persist state after voting

Persist state after handling self vote to avoid double voting in case
of voter restarts.

* client/beefy: persist state after handling mandatory block vote

For mandatory blocks we want to make sure we're not losing votes
in case of crashes or restarts, since voter will not make further
progress without finalizing them.

* frame/beefy: use GENESIS_AUTHORITY_SET_ID on pallet genesis

* client/beefy: initialize voter at either genesis or last finalized
To guarantee unbroken chain of mandatory blocks justifications, voter
will always resume from either last BEEFY-justified block or
`pallet-beefy` genesis, whichever is more recent.

Initialization walks back the chain from latest GRANDPA finalized
block looking for one of the above. Along the way, it also records
and enqueues for processing any BEEFY mandatory blocks that have
been already GRANDPA finalized but not BEEFY finalized.
