osd/PG: force rebuild of missing set on jewel upgrade

Previously we were detecting the need to rebuild missing based on
whether the "divergent_priors" omap key was present.  Unfortunately,
jewel does not always set this, so it is not a reliable indicator.
(It only gets set if you actually have a divergent prior at some
point in the PG's life time on that OSD.)

Fix by using the info_struct_v on the PG to detect whether we need
to do the conversion.  We didn't bump the value when we adding
the missing persistence, but the fastinfo was also added during
the same period between jewel and kraken, so it will work just as
well.

rbd: parallelize rbd ls -l

When a cluster contains a large number of images, "rbd ls -l" takes a
long time to finish. In my particular case, it took about 58s to
process 3000 images.
"rbd ls -l" opens each of image and that takes majority of time, so
improve this by using aio_open() and aio_close() to do it
asynchronously. This reduced total processing time down to around 15
seconds when using default 10 concurrently opened images.
