Inherents and empty block production overhaul (#86)

A pre-requisite to producing empty blocks for MBMs is fixing inherents
for relay and parachains, and moving block production logic from being
tied to `fast_forward` to common logic.

It will also be very beneficial to allow producing blocks based on a
snapshot, without any live node (`--block-ws-uri`).

Based on the changes in this PR, I'll add MBM support to the
`on-runtime-upgrade` subcommand.

- Fixes inherent providers for relay and parachains
- Introduces a SMART inherent provider designed to work across different
chains, removing the requirement for a cli arg to specify which
inherents to use
- Moves inherent and block production to a common utils dir
- Removes requirement for a remote node to produce empty blocks
- Closes #32 (no longer compiles kitchensink runtime)
