Rework stripe creation path - new algorithm for deciding when to create new stripes or reuse existing stripes. We add a new allocation watermark, RESERVE_stripe, above RESERVE_none. Then we always try to create a new stripe by doing RESERVE_stripe allocations; if this fails, we reuse an existing stripe and allocate buckets for it with the reserve watermark for the given write (RESERVE_none or RESERVE_movinggc).
