crush: set default tunables to jewel
For new clusters.

This is the last "disruptive" tunable change we've made (where adjusting/
fixing it requires lots of data movement).  For new clusters a lower bound
of jewel seems pretty reasonable, and this has been upstream in Linux
for a while now.

mon: set mon_osd_initial_require_min_compat_client = jewel
IMO a jewel lower bound is reasonable for new clusters.

test/cli/crushtool: adjust tests
Specify chooseleaf_stable for --build tests to match prior output.

test/cli/osdmaptool/: fix tests
CRUSH tunables now default to jewel; outputs vary and
upmap results are a bit different.
