Add support for multi-sig accounts to stake program

[danpaul000]

Problem

High value stake accounts should be able to be secured via a withdraw authority that is a multi-sig account

Proposed Solution

Add support for multi-sig to stake program for account authorities.

I think we do this by adding a generic SPL multisig program and then setting it as the withdraw or stake authority. This'll require Ledger support for the multisig program as well

@mvines, has anyone done that? I'd love to see that code.

It uses the Anchor framework though. Would be nice to get an audit on both
