This adds one Jaeger span per relay parent, instead of always creating
new spans per relay parent. This should improve the UI view, because
subsystems are now grouped below one common span.

* update tiny-keccak to 0.2

* update deps except bitvec and shared_memory

* fix some warning after futures upgrade

* remove useless package rename caused by bug in cargo-upgrade

* revert parity-util-mem *

* remove unused import

* cargo update

* remove all renames on parity-scale-codec

* remove the leftovers

* remove unused dep

* 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.

.

Closes #1757.

We now have some evidence that the polkadot validator was producing
blocks after all; the reason the blocks_constructed metric was 0 was
that as a new metric it hadn't yet been incorporated into that
branch's codebase. See
https://github.com/paritytech/polkadot/issues/1757#issuecomment-700977602

As this PR is based on a newer `master` branch than the previous one,
that should hopefully no longer be an issue.

* wip: rococo readme

* remove /service crate

- Move the chain-spec files to node-service
- update sufficient cargo files that polkadot-service-new builds
- not everything else builds yet

* wip: chase down some build errors in polkadot-cli

There's a lot more to go, but some progress has happened.

* make more progress getting polkadot-cli to build

* don't ignore polkadot.json within the res directory

* don't recreate pathbufs

* Prepare Polkadot to be used by Cumulus

This begins to make Polkadot usable from Cumulus.

* Remove old test

* migrate new_chain_ops fix from /service

* partially remove node/test-service

* Reset some changes

* Revert "partially remove node/test-service"

This reverts commit 7b8f9ba5.

* WIP: replace v0 ParachainHost impl with v1 for test runtime

This is necessary because one of the current errors when building
the test service boils down to:

the trait bound `polkadot_test_runtime::RuntimeApiImpl<...>`:
  `polkadot_primitives::v1::ParachainHost<...>` is not satisfied

This is WIP because it appears to be causing some std leakage into
the wasm environment, or something; the compiler is currently
complaining about duplicate definitions of `panic_handler` and `oom`.
Presumably I have to identify all std types (Vec etc) and replace
them with sp_std equivalents.

* fix test runtime build

it wasn't std leakage, after all

* bump westend spec version

* use service-new as service within cli

* to revert: demo that forwarding the test runtime to the real impl blows up

* Revert "to revert: demo that forwarding the test runtime to the real impl blows up"

This reverts commit 68d2f385.

* Revert "Revert "to revert: demo that forwarding the test runtime to the real impl blows up""

This reverts commit 04cb1cbf.

Might have just forgotten to disable default features

* More reverts

* MOARE

* plug in the runtime as the generic instantiation

This feels closer to a solution, but it still has problems: in particular,
it's assumed that Runtime implements all appropriate Trait traits,
which this one apparently does not.

* implement necessary traits to get the test runtime compiling

This is almost certainly not correct in some way; it really
looks like I need to mess with the construct_runtime! macro
somehow, to inject the inclusion trait's event type as a Event
variant. Still, better lock down this changeset while it all
compiles.

* add inclusion::Event as variant into Event enum

* implement unimplemented bits in kusama

* implement unimplemented bits in polkadot runtime

* implement unimplemented bits in westend runtime

* migrate client upgrades from master

* update test service with new node changes

* package metadata--that wasn't intended to be removed

* add parachains v1 modules to each runtime

It's not clear what precisely this does, but it's probably the right
thing to do.

* enable cli to opt out of full node features

* adjust rococo chainspec per example

https://github.com/paritytech/polkadot/blob/26f1fa47

/service/src/chain_spec.rs#L362

It doesn't look like we use the actual commitments data anywhere, and
it's not obvious if there are any fields of `CandidateCommitments`
not available to the collator, so this commit just assigns them the
entire responsibility of generating the hash.
