Substrate PoA

A sample Substrate runtime for a PoA blockchain that allows:

• Dynamically add/remove authorities.
• Automatically remove authorities when they go offline, to recover block period.
• Add authorities again when they come back online.

The runtime uses the Substrate Validator Set pallet for the above functionalities.
