Description

the new flag in osdmap will affects the osd up according option
mon_osd_auto_mark_new_in. So it is more safe to clear the new flag when
destroy osd. the follow sequence may cause new osd can not up.

1. ceph osd new
2. do not start daemon, so the new flag will exist.
3. ceph osd destroy the osd, the destoryed flag add, but new flag
remain to exist. then the new state is :
"state": [
"destroyed",
"exists",
"new"
]
5. if we new the osd again, the new flag will flip ,and the state will become:
"state": [
"exists",
]
6. becase the new flag do not exist, so the osd boot and can not up when
the option mon_osd_auto_mark_new_in is true
