Generates a proof of key ownership for the given authority in the
given set. An example usage of this module is coupled with the
session historical module to prove that a given authority key is
tied to a given staking identity during a specific session. Proofs
of key ownership are necessary for submitting equivocation reports.
NOTE: even though the API takes a set_id as parameter the current
implementations ignores this parameter and instead relies on this
method being called at the correct block height, i.e. any point at
which the given set id is live on-chain. Future implementations will
instead use indexed data through an offchain worker, not requiring
older states to be available.
