Fix `--parachain-id` CLI argument for `export-genesis-state` and don't
print genesis state without newline.

* One node two runtimes

This enables the rococo-collator to run the normal and the contracts runtime.

* Fix tests

This reworks the default values used by the RelayChainCli for stuff like
the listen port etc.

This also renames all the contracts related stuff to `cumulus-*` to
support `.cargo/config` overrides.

* Add cumulus-service

Crate that abstracts the service of a parachain.

* Make finalization infallible

* Separate paraid injection to own pallet

* Move token dealer to a crate

* Move to rococo-parachains

* Remove parameter_types hack

* Fix chainspec

* fix build

* remove commented code

* Update contracts runtime to match other runtime

* Apply suggestions from code review
