Problem
During a cluster restart, it's possible for stake accounts to get force destaked. If a stake pool contains a force destaked validator stake account, many parts will stop working.
Solution
Provide two safeguards:
Initialized, assume that a destake happened, merge it into the reserve, and effectively remove that validator from the pool. It can always be re-added again if needed.Initialized, something bad happened, so prevent the increase. This is in the case of a cronjob that isn't aware that a force destake happened, and tries to increase stake on the validator.
