* Introduce generalised proxies to polkadot

* Introduce proxy to westend

* Add proxy to Kusama.

* Fix

* migrate subsystem expansion PR from w3f/research

As the file at this new location included changes not present in
https://github.com/w3f/research/pull/87, this is effectively a
rebase, applied manually. I believe that I have successfully retained
all of, and only, the intended changes.

* add section on collators

* note why the overseer is the terminal message point for the validation subsystem

* add detail about how the validitiy system gets PoV blocks

* rename to Validity Subsystems Overview

* get rid of changes to the implementor's guide

I think it makes most sense to track and review the subsystems
overview in a different PR than the one which adds content to
the implementor's guide.

* punt misbehavior arbitration details to the future

* empty commit to rerun CI

* Add block event forwarding into the Overseer

* Add a doc comment

* Fix a doc comment

* Adds start and stop work heartbeats.

* Apply suggestions from code review

This pr ensures that the table router stays alive for the lifetime of
the validation instance. This is required to ensure that the node
responds onto gossip messages for the particular relay chain round.
Before, the table router was only kept alive for relay chain nodes that
were assigned to a Parachain, however the lifetime was also relative
short. This lead to bugs where a relay chain node did not include
PoVBlock's, because it did not receive them (rejected them on receive,
because it was not listening on the particular round).

This lets offline signers know that the transaction format has changed,
due to the addition of `transaction_version` to the signed payload.

* Make sure that vested claims are not transferable

We need to deposit the claimed balance to the destination account before
setting the locks through the vesting module. Otherwise we loose the
locks and the vested claim is directly transferable.
