This is unlikely to be noticed by anybody, but it is a big change. Document
in the PendingReleaseNotes and bump up the librados minor version number
to 68.

This method is problematic because it both writes/mutates and returns data,
which means that an untimely client disconnect or peering event will result
in a success to the client with no payload.
It has not been used since v0.52 (18054ba46f)
which is pre-bobtail; so this change breaks compatibility with pre-bobtail
librbd clients (at least for image creation).

We can live with the incompatibility here; the hack is currently
not working anyway (see #5623).

The previous 'osd scrub min interval' was mostly meaningless and useless.
Meanwhile, the 'osd scrub max interval' would only trigger a scrub if the
load was sufficiently low; if it was high, the PG might *never* scrub.
Instead, make the 'min' what the max used to be. If it has been more than
this many seconds, and the load is low, scrub. And add an additional
condition that if it has been more than the max threshold, scrub the PG
no matter what--regardless of the load.
Note that this does not change the default scrub interval for less-loaded
clusters, but it *does* change the meaning of existing config options.
