test/osd: add perf test for calc_pg_upmaps with mutual overfull upmap pairs

Reproduces the scenario from https://tracker.ceph.com/issues/63137: 500
cohort OSDs all at deviation +2, linked by pg_upmap_items rings with R=5
pairs each.  Before the fix, every incoming pair triggered a test_change
call that got rejected -- calc_pg_upmaps took ~11 minutes.  After, it
exits in ~200ms.
