* refactor out validation hosts to pool struct

* make web-wasm compatible

* typo

* remove now-unused static hosts

* Ensure that table router is always build

This pr ensures that the table router is always build, aka the future is
resolved. This is important, as the table router internally spawns tasks
to handle gossip messages. Handling gossip messages is not only required
on parachain validators, but also on relay chain validators to receive collations.

Tests are added to ensure that the assumptions hold.

* Fix compilation

* Switch to closures

Before the validator only send the keys if it was updated and thus the
collators would "never" be informed about the key of the validator.

Up to now consensus instances used the main channel to communicate with
the background network worker. This lead to a race condition when
sending a local collation and dropping the router before driving the
send local collation future until it is finished. This pr changes the
communication between worker and the instances to use their own
channels. This has the advantage that we don't need an extra
`DropConsensusNetworking` message as the network is dropped
automatically when the last sender is dropped.

Updating the heads was accidentally removed in some other pr.
