* Companion for Substrate#7318

* "Update Substrate"

Co-authored-by: parity-processbot <>

This reverts commit 671cc75c.

The authority discovery module was initially enabled by default on
validator and sentry nodes with commit bc6e1e77. This change was later on
reverted in 671cc75c. With this commit the authority discovery module is
again enabled by default.

They are not node handles anymore ;)

The collator is now enabled in a different way and we don't require this
argument anymore.

i.e.
Revert "Revert "Remove Old Service, 2nd try (#1732)" (#1758)"

This reverts commit c80f7b6b.

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.

* paras trait now has an Origin type

* initial work running a two node local net

* use the right incantations so the nodes produce blocks together

* improve internal documentation

* Make `AllSubsystems` usage easier in tests

This makes the usage of `AllSubsystems` easier in tests by introducing
new methods.

- `dummy` initializes `AllSubsystems` with all systems set to dummy
- `replace_*` to replace any subsystem

Besides that this pr adds a `ForwardSubsystem` that is also useful for
tests. This subsystem will forward all incoming messages to the given channel.
