Problem
Currently, on-chain programs have no knowledge of the current epoch's stake and
how much active stake is delegated to a certain vote account.
If this data was available for querying by on-chain programs, it would unblock
many use cases, such as validator governance and secondary consensus mechanisms,
that were previously not possible on Solana.
Additionally, this would enable the Feature Gate program defined in
SIMD 0089 to tally vote account stake in
support for a pending feature gate.
Summary of Changes
