Adds API for fast shutdown - the ability for FTL to skip most
of the metadata persists made during clean shutdown, and relying
on their representation in shared memory instead. This allows for
faster update of SPDK (or just FTL, assuming no metadata changes),
with downtime reduction from 2-5 seconds to 500-1000 ms (for
14TiB+800GiB base and cache drives).
