Remove Old Service, 2nd try (#1732)

* Restore "Remove service, migrate all to service-new (#1630)"

i.e.
Revert "Revert "Remove service, migrate all to service-new (#1630)" (#1731)"

This reverts commit b4457f555b.

This allows us to get the changeset from #1630 into a new branch
which can be merged sometime in the future after appropriate burnin
tests have completed.

* remove ',)' from codebase outside of macros

* restore bdfl-preferred formatting

* attempt to improve destructuring formatting

* rename polkadot-service-new -> polkadot-service

* Apply suggestions from code review

* remove unused import

* Update runtime/rococo-v1/README.md
