osd: shutdown our reserver_finisher earlier in the process

This finisher thread has a lot of callbacks which can hold PGRefs. Make
sure we drain them out before checking that all the PGs have finished
and have no outstanding references.

Moving this should be safe; we've already stopped the op thread et al
and the only things still running are the OSDService's objecter_finisher,
recovery_request_timer, and snap_sleep_timer (which has definitely been emptied

rgw: set object accounted size correctly

sometimes, object accounted size is set wrong,
because we don't konw the object size if don't resort to the compression info or manifest.
e.g, when i use s3cmd do copy object(bucket_A/obj_A -> bucket_B/obj_B, assume the size of obj_A is 4M).
then i use s3cmd do list bucket, I got obj_B size is 512K, it is the head size apparently.

rgw: swift: disable revocation thread if sleep == 0 || cache_size == 0

Keystone tokens can be revoked.  This causes them to fail
validation.  However, in ceph, we cache them.  As long as
they're in the cache we trust them.  To find revoked tokens
there's a call OSI-PKI/revoked but that's only useful for
pki tokens.  Installations using fernet/uuid may not even
have the proper credentials to support the call, in which
case the call blows up in various ways filling up logs
with complaints.

This code makes the revocation thread optional; by disabling it,
the complaints go away.  A further fix is in the works
to use other more modern calls available in modern keystone
installations to properly deal with non-PKI/PKIZ tokens.

To disable the revocation thread, use at least one of these:
        rgw_keystone_token_cache_size = 0
using this will cause tokens to be validated on every call.
You may instead want to set
        rgw_keystone_revocation_interval = 0
using just this will disable the revocation thread,
but leaves the cache in use.  That avoids the extra
validation overhead, but means token revocation won't
work very well.
