commit 4b59d31390d61016525eb2bd4537027ec72e54c6 (HEAD -> ceph-5.0-rhel-patches, patches/ceph-5.0-rhel-patches)

    mon: MonMap: do not increase mon_info_t's compatv in stretch mode, for real
    
    This was supposed to be fixed a year ago in commit
    2e3643647bfbe955b54c62c8aaf114744dedb86e, but it set compat_v to 4 instead of all
    the way back to 1 as it should have.
    
    Our testing for stretch mode in these areas is just not very thorough -- the
    kernel only supports compat_v 1 and apparently nobody's noticed the issue
    since then? :/
    As the prior commit says, you can't set locations without being gated on a
    server feature bit, so simply cancelling this enforcement is completely safe.
