osd/SnapMirror: no need to record purged_snaps every epoch

These keys were a mirror of the mon's purged_epoch keys.  We were writing
them, but never looking at them.  We only need the per-pool keys that
are indexed by snapid for lookups, so we should stop storing the per-epoch
records.

Note that the OSDSuperblock has the purged_snaps_last that serves as our
position/cursor for ingesting the mon keys.

osd/PeeringState: clear LAGGY and WAIT states on exiting Started

These flags were not getting cleared except in recheck_readable(), which
meant that a flag from a prior interval could bleed into a new interval.
More dangerously, in a mixed-version cluster, one interval might include
all octopus+ OSDs while the next might include a pre-octopus OSD, bypassing
most of the laggy recheck code.  This could lead to a stalled request
and/or requeue ordering bug when release_object_locks() looked at

test/librados: free AioCompletion using unique_ptr

librados: release pimpl pointer in destructor

before this change, the librados applications are responsible to call
`AioCompletion::release()` explicitly to release its internal pimpl
pointer. this is error prone and not intuitive.

after this change, the destructor of `AioCompletion` and
`PoolAsyncCompletion` will do this automatically. while
`AioCompletion::release()` and `PoolAsyncCompletion::release()` still
delete the instance as they did before. so this change is backward
compatible, as existing librados clients can still use `ptr->release()`
to free the completion instance, while new clients can just `delete
ptr`.

librados_test_stub is updated accordingly to match the new model
