Instruction: ReactivatePoolStake

This instruction can be used to restake the pool stake account. This instruction is needed if the stake is deactivated for any reason. Currently, a stake can be forcefully deactivated by inactivity (via the stake program DeactivateDelinquent instruction) or due to a cluster restart.

The instruction is unpermissioned; this is safe, since the stake is committed to the vote account associated with the pool. Stake accounts that have been deactivated due to natural expiry are forbidden from being restaked.
