* client/network-gossip/src/bridge: Finish when network even stream closes

Previously within `<GossipEngine as Future>::poll` one would poll the
`network_event_stream` ignoring all messages other than
`Poll::Ready(Some())`. Ignoring `Poll::Ready(None)` leads to a panic on
the next poll of the stream, gien that it is not fused.

By design `network_event_stream` does not close unless an unbounded send
into it fails, or the `NetworkWorker` gets shut down.

> The stream never ends (unless the `NetworkWorker` gets shut down).
> (client/network/src/service.rs)

An `unbounded_send` to fail on an unbounded channel is unlikely. The
`NetworkWorker` shutting down is not unlikely. In such case the
`GossipEngine` should shut down as well.

With this patch a `<GossipEngine as Future>` finishes on
`Poll::Ready(None)` returned from `network_event_stream`.

* client/finality-grandpa/communication: Error on gossip engine finished

Have `<NetworkBridge as Future>::poll` return `Poll::Ready(Err)` instead
of `Poll::Ready(Ok)` to be consistent with the handling of the neighbor
packet worker stream and the gossip validator report stream. Both `Err`
as well as `Ok` shut down the `NetworkBridge` as well as the
`VoterWorker`.

If polling encounters a `Poll::Pending` we need to return it instead of
continuing the loop which may turn it into a blocking operation, causing
problems with executors.

With this patch forward this will be the only way for
a contract to destroy itself. This patch therefore changes
the semantics of all other contract initiated balance
transfers to fail if they would bring the caller below the
existential deposit.

* client/network/src/protocol: Start Prometheus metric help with capital

* client/network/src/protocol: Differentiate metric status as label

Prometheus query language is powerful through its multi-dimensional data
model. Metric names are hirarchical whereas labels enable data to become
multi-dimensional.

Exposing the justification of finality-proof status as a label allows
for more powerful queries.

* client/network/src/protocol: Remove 'Total' from non counter metric help

The word 'total' is reserved for accumulating counters. Counters have to
be monotonically increasing. `obsolete_requests` can decrease, thereby
it is defined as a `Gauge` and not a `Counter`.

For more details on metric naming see
https://prometheus.io/docs/practices/naming/

* Move runtime upgrade to `frame-executive`

Instead of storing the runtime upgraded in the space of `frame-system`,
this moves it to `frame-executive`. We also start storing the
`spec_version` and `impl_version` the last runtime upgrade was applied.

This scheme has multiple advantages:
- We don't need to make sure that runtime upgrade was set.
- This will work in the future when we want to test a runtime upgrade,
because the `on_runtime_upgrade` will be executed automatically when the
runtime changes.

* Move `LAST_RUNTIME_UPGRADE` key to `frame-executive`

* Add some more documentation

* Make sure `spec_version` always increases between runtime upgrades

* Fix test

* Upgrade `parity-multiaddr` to fix compilation

* Also check if the `spec_name` changed
