* service/src/lib: Update authority discovery construction

https://github.com/paritytech/substrate/pull/6760 introduces the concept
of an authority discovery `Service` allowing one to communicate with an
authority discovery `Worker`, e.g. to learn the `Multiaddr`s for a given
`AuthorityId`.

Along with the new `Service` structure it also alters the authority
discovery constructor to return both a worker and a service. This
commit adjusts the callside of the constructor, ignoring the `Service`
for now.

* Update Substrate

Co-authored-by: parity-processbot <>

While editing the impl guide markdowns I tried to be inline with what seemingly more
common way to indent them: spaces. However, despite that I changed it kept reseting.
Turned out the culprit is the .editorconfig file.

This commit addresses this issue. I didn't try to deduplicate the rules since
I found that the formal specification is a bit ambigious and it is not a big
deal anyway.

* Support `build-spec` for other chains than Polkadot

The problem when building a chain specification is that you require the
native runtime to parse the json file (assuming the chain spec is not
raw yet). Before this pr we could only overwrite the native runtime when
running the node using `force_*`. This pr now adds support to load the
native runtime when the filename starts with the name of the chain. So,
when usng `build-spec --chain rococo-something-else.jon` it will use the
rococo native runtime to load the chain spec.
