chore(docker-dev-chain-init): [ETH-880] Remove subpackage (#1000)

Removed the obsolete `docker-dev-chain-init` subpackage. This subpackage
dated back to the Parity node era.

The `dev-chain-fast` subpackage, which we use today, initializes itself
(in deploy.ts), so a separate initialization module is no longer
necessary.
