* Implement `Debug` manually for CandidateHash
This will make candidate hashes printed consistently without the
`CandidateHash(` and `)` decorations.
* Do not print CompressedPov's guts
It can be overwhelming. Better just use the size.
* Log when candidate is generated
* Print para_id and candidate_hash upon receiving a collation
* Move NetworkBridgeEvent to subsystem::messages.
It is not protocol related at all, it is in fact only part of the
subsystem communication as it gets wrapped into messages of each
subsystem.
* Request/response infrastructure is taking shape.
WIP: Does not compile.
* Multiplexer variant not supported by Rusts type system.
* request_response::request type checks.
* Cleanup.
* Minor fixes for request_response.
* Implement request sending + move multiplexer.
Request multiplexer is moved to bridge, as there the implementation is
more straight forward as we can specialize on `AllMessages` for the
multiplexing target.
Sending of requests is mostly complete, apart from a few `From`
instances. Receiving is also almost done, initializtion needs to be
fixed and the multiplexer needs to be invoked.
* Remove obsolete multiplexer.
* Initialize bridge with multiplexer.
* Finish generic request sending/receiving.
Subsystems are now able to receive and send requests and responses via
the overseer.
* Doc update.
* Fixes.
* Link issue for not yet implemented code.
* Fixes suggested by @ordian - thanks!
- start encoding at 0
- don't crash on zero protocols
- don't panic on not yet implemented request handling
* Update node/network/protocol/src/request_response/v1.rs
Use index 0 instead of 1.

* Compress the PoV block before sending it over the network
This pr changes the way we send PoV blocks over the network. We now
compress the PoV block before it is send over the network. This should
reduce the size significant for PoVs which contain the runtime WASM for
example.

* Improve collator side of the collator-protocol
This pr improves the collator-protocol implementation of the collator
side. Besides cleaning up code and rewriting it, the following changed:
- Before on `PeerViewChange` we send an advertisment to every peer, now
this only happens for validators.
- It also adds a check that we send an advertisment message only once
for a connected peer.
- If the same validator was part of the current and next group, we
requested to be connected to this validator two times. This is also
fixed now.
- Instead of having only one connection request, we now are being able
to store multiple of them. This is required as we can have multiple
active leafs at any point of time.
* Switch to common `ConnectionRequests`
* Update node/network/collator-protocol/src/collator_side.rs
* use snake_case for log targets
* remove unused continue
* validator_discovery: when disconnecting, use all addresses
* validator_discovery: simplify request revokation
* fix a typo
* reexport prometheus-super for ease of use of other subsystems
* add some prometheus timers for collation generation subsystem
* add timing metrics to av-store
* add metrics to candidate backing
* add timing metric to bitfield signing
* add timing metrics to candidate selection
* add timing metrics to candidate-validation
* add timing metrics to chain-api
* add timing metrics to provisioner
* add timing metrics to runtime-api
* add timing metrics to availability-distribution
* add timing metrics to bitfield-distribution
* add timing metrics to collator protocol: collator side
* add timing metrics to collator protocol: validator side
* fix candidate validation test failures
* add timing metrics to pov distribution
* add timing metrics to statement-distribution
* use substrate_prometheus_endpoint prometheus reexport instead of prometheus_super
* don't include JOB_DELAY in bitfield-signing metrics
* give adder-collator ability to easily export its genesis-state and validation code
* wip: adder-collator pushbutton script
* don't attempt to register the adder-collator automatically
Instead, get these values with
```sh
target/release/adder-collator export-genesis-state
target/release/adder-collator export-genesis-wasm
```
And then register the parachain on https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer
To collect prometheus data, after running the script, create `prometheus.yml` per the instructions
at https://www.notion.so/paritytechnologies/Setting-up-Prometheus-locally-835cb3a9df7541a781c381006252b5ff
and then run:
```sh
docker run -v `pwd`/prometheus.yml:/etc/prometheus/prometheus.yml:z --network host prom/prometheus
```
Demonstrates that data makes it across to prometheus, though it is likely to be useful in the future
to tweak the buckets.

* start working on building the real overseer
Unfortunately, this fails to compile right now due to an upstream
failure to compile which is probably brought on by a recent upgrade
to rustc v1.47.
* fill in AllSubsystems internal constructors
* replace fn make_metrics with Metrics::attempt_to_register
* update to account for #1740
* remove Metrics::register, rename Metrics::attempt_to_register
* add 'static bounds to real_overseer type params
* pass authority_discovery and network_service to real_overseer
It's not straightforwardly obvious that this is the best way to handle
the case when there is no authority discovery service, but it seems
to be the best option available at the moment.
* select a proper database configuration for the availability store db
* use subdirectory for av-store database path
* apply Basti's patch which avoids needing to parameterize everything on Block
* simplify path extraction
* get all tests to compile
* Fix Prometheus double-registry error
for debugging purposes, added this to node/subsystem-util/src/lib.rs:472-476:
```rust
Some(registry) => Self::try_register(registry).map_err(|err| {
eprintln!("PrometheusError calling {}::register: {:?}", std::any::type_name::<Self>(), err);
err
}),
```
That pointed out where the registration was failing, which led to
this fix. The test still doesn't pass, but it now fails in a new
and different way!
* authorities must have authority discovery, but not necessarily overseer handlers
* fix broken SpawnedSubsystem impls
detailed logging determined that using the `Box::new` style of
future generation, the `self.run` method was never being called,
leading to dropped receivers / closed senders for those subsystems,
causing the overseer to shut down immediately.
This is not the final fix needed to get things working properly,
but it's a good start.
* use prometheus properly
Prometheus lets us register simple counters, which aren't very
interesting. It also allows us to register CounterVecs, which are.
With a CounterVec, you can provide a set of labels, which can
later be used to filter the counts.
We were using them wrong, though. This pattern was repeated in a
variety of places in the code:
```rust
// panics with an cardinality mismatch
let my_counter = register(CounterVec::new(opts, &["succeeded", "failed"])?, registry)?;
my_counter.with_label_values(&["succeeded"]).inc()
```
The problem is that the labels provided in the constructor are not
the set of legal values which can be annotated, but a set of individual
label names which can have individual, arbitrary values.
This commit fixes that.

This pr changes the collator interface function to return an optional
collation instead of a collation. This is required as the parachain
itself can fail to generate a valid collation for various reason. Now if
the collation fails it will return `None`.
Besides that the pr adds some `RuntimeDebug` derive for `ValidationData`
and removes some whitespaces.
