Import `IterableStorageMap` and `IterableStorageDoubleMap` automatically
by `decl_storage!` as the other storage traits.

* Add support for sourced metrics.

A sourced metric is a metric that obtains its values
from an existing source, rather than the values being
independently recorded. It thus allows collecting
metrics from existing counters or gauges without
having to duplicate them in a dedicated prometheus
counter or gauge (and hence another atomic value).

The first use-case is to feed the bandwidth counters
from libp2p directly into prometheus.

* Tabs, not spaces.

* Tweak bandwidth counter registration.

* Add debug assertion for variable labels and values.

* Document monotonicity requirement for sourced counters.

* CI

* Update client/network/src/service.rs

It makes no sense that `can_set_code` takes the origin for checking it.
Everybody reusing this function is only interested in the other checks
that are done by this function. The origin should be checked by every
dispatchable individually.

Revert the accidental query interval change from every one minute back
to every 10 minutes.

* Update to libp2p-0.23.

Thereby incorporate bandwidth measurement along the
lines previously done by libp2p itself.

* Tweak dependencies for wasm32 compilation.

For wasm32 we need to enable unstable features to
make `task::Builder::local` available.

* Simplify dependencies.

* Simplify.

Leave the calculation of bytes sent/received per second
to the outer layers of the code, subject to their own
individual update intervals.

* Cleanup

* Re-add lost dev dependency.

* Avoid division by zero.

* Remove redundant metric.

* Enable sending of noise legacy handshakes.

* Add comment about monotonic gauge.

* pallet-evm: avoid double fee payment

* Only skip fee payment for successful calls

Actually I use this quite often when debugging some WASM bugs and there
is no harm in enabling it by default. Before I just always copied it
everytime I needed it.

* client/authority-discovery: Rename AuthorityDiscovery to XXXWorker

* client/authority-discovery: Introduce AuthorityDiscoveryService

Add a basic `AuthorityDiscoveryService` implementation which enables
callers to get the addresses for a given `AuthorityId` from the local
cache.

* client/authority-discovery: Split into worker and service mod

Move `Service` and `Worker` to their own Rust modules resulting in the
following file structure.

├── build.rs
├── Cargo.toml
└── src
    ├── error.rs
    ├── lib.rs
    ├── service.rs
    ├── tests.rs
    ├── worker

    │   ├── schema
    │   │   └── dht.proto
    │   └── tests.rs
    └── worker.rs

* client/authority-discovery: Cache PeerId -> AuthorityId mapping

* client/authority-discovery: Update priority group on interval

Instead of updating the authority discovery peerset priority group each
time a new DHT value is found, update it regularly on an interval.

This removes the need for deterministic random selection. Instead of
trying to return a random stable set of `Multiaddr`s, the `AddrCache`
now returns a random set on each call.

* client/authority-discovery: Implement Service::get_authority_id

* client/authority-discovery: Use HashMap instead of BTreeMap

* client/authority-discovery: Rework priority group interval

* client/authority-discovery: Fix comment

* bin/node/cli: Update authority discovery constructor

* client/authority-discovery: Fuse from_service receiver

* client/authority-discovery: Remove Rng import

* client/authority-discovery: Ignore Multiaddr without PeerId

* client/authority-discovery/service: Add note on returned None

* client/authority-discovery/addr_cache: Replace double clone with deref
