The `NeighborPacketWorker` within `client/finality-grandpa` does two
things:
1. It receives neighbor packets from components within
`client/finality-grandpa`, sends them down to the `GossipEngine` in
order for neighboring nodes to receive.
2. It periodically sends out the most recent neighbor packet to the
`GossipEngine`.
In order to send out packets it had a clone to a `GossipEgine` within
an atomic reference counter and a mutex. The `NeighborPacketWorker` was
then spawned onto its own asynchronous task.
Instead of running in its own task, this patch reintegrates the
`NeighborPacketWorker` into the main `client/finality-grandpa` task not
requiring the `NeighborPacketWorker` to own a clone of the
`GossipEngine`.
The greater picture
This is a tiny change within a greater refactoring. The overall goal is
to **simplify** how finality-grandpa interacts with the network and to
**reduce** the amount of **unbounded channels** within the logic.
Why no unbounded channels: Bounding channels is needed for backpressure
and proper scheduling. With unbounded channels there is no way of
telling the producer side to slow down for the consumer side to catch
up. Rephrased, there is no way for the scheduler to know when to favour
the consumer task over the producer task on a crowded channel and the
other way round for an empty channel.
Reducing the amount of shared ownership simplifies the logic and enables
one to use async-await syntax-suggar, given that one does not need to
hold a lock across poll invocations. Using async-await enables one to
use bounded channels without complex logic.
* Implement runtime version checks in `set_code`
Check that the new runtime code given to `set_code` fullfills some
requirements:
- `spec_name` matches
- `spec_version` does not decreases
- `impl_version` does not decreases
- Either `spec_version` and `impl_version` increase

Instead of having these weird implementation of `BuildStorage for
&ChainSpec` we should just take the `genesis_storage` by ref. The
`BuildStorage` trait changed some time ago to take a self ref anyway,
instead of a self value.

Previously one would create a sender and receiver channel pair, pass the
sender to the `build_network_future` through the service builder and
funnel network events returned from polling the network service into the
sender to be consumed by the authority discovery module owning the
receiver.
With recent changes it is now possible to register an `event_stream`
with the network service directly, thus one does not need to make the
detour through the `build_network_future`.
* client/authority-discovery: Limit number of connections to authorities
Instead of connecting to all sentry nodes of all authorities, with this
patch the authority discovery module does the following:
- Choose one sentry node per authority at random.
- Choose MAX_NUM_AUTHORITY_CONN out of the above at random.
The module uses randomness to prevent hot spots, e.g. all nodes trying
to connect to a single node. If the authority discovery module would
choose the nodes to connect to at random on each new address that it
learns of, the node would go through a lot of connection churn. Instead
it creates a random seed at start up and uses this seed for its RNG on
each update cycle.
* client/authority-discovery: Extract address cache into own module
* client/authority-discovery/src/addr_cache: Add basic unit tests
* client/authority-discovery: Replace unwrap with expect on [u8] cmp
* .maintain/sentry-node/docker-compose.yml: Prefix endpoint flags
* client/authority-discovery/src/addr_cache: Use sort_unstable and cmp
* client/authority-discovery: Use BTreeMap in addr_cache for sorted iter
To reduce connection churn it is preferrable to have `get_subset` of the
`addr_cache` to return the same result on repeated calls. `get_subset`
iterates a map. To make the process of iteration deterministic, use a
`BTreeMap` instead of a `HashMap`.
