Code Issues Proposed changes

Disable ceph osd crush update on start in default

Browse Source 
The buggy come from ceph changes[0], which is included since ceph osd
v11.0.0. The `osd crush update on start` logical is moved from
`ceph-osd-prestart.sh` to ceph-osd startup process. So ceph-osd will
create buckets by node hostname automatically. Whereas, kolla is
creating buckets by node ip

For the less confused and ceph upgrade impact, disable `osd crush update
on start` is a better choice
