If it's just one or two commits, we could backport (please fill in the Backport field in that case). But 131 commits?

commit d6d1db62edeb4c40a774fcb56e7619b2997ff2d0

mgr: apply PGMap incremental at same interval as reports
We were doing an incremental per osd stat report; this screws up the
    delta stats updates when there are more than a handful of OSDs.  Instead,
    do it with the same period as the mgr->mon reports.
