This PR aims to provide a better abstraction to handle and report equivocations/offences.
The refactory introduces a new trait
OffenceReportSystemthat should be used when a component requires a higher level subsystem to wrap some of the operations typically required during an offence report:The introduced trait usage is not limited to the consensus equivocation reports but can be used for any type of offence that requires these three typical actions
Furthermore the refactory removes some burden from the user during instantiation of the pallet by providing a simpler interface.
Beside the simplification and encapsulation of some of the procedures, the PR also wants to be a starting point for:
This trait can also be used by Beefy to report equivocations
