get_recovery_allowances

Answer "can I still run a recovery, or do I need support?". Self-service recovery is allowed once per kind (account, bot, resources) inside a rolling window; beyond that, support reviews the account and may release a grant. Each row carries what the window still allows (self_service_remaining), what support has released and not yet spent (grant_remaining), their sum (remaining), whether a recovery of that kind would be allowed right now (allowed), whether the next one would spend a grant (uses_grant), when the kind was last recovered and when the self-service allowance returns. meta carries the window itself. The rows are the ones GET /v1/recovery/allowances returns.
