Allow Kolla Ceph to deploy bluestore OSDs in Kolla

Browse Source 
Support Kolla Ceph to deploy blustore OSDs. With the patch, Kolla
Ceph can deploy bluestore OSDs on ONE, TWO or THREE storage
devices.

Before deploy bluestore OSD, please prepare devices. The detailed
Please refer to [1] for devices initialization.

extend_start.sh: initialize and start bluestore OSD

find_disk.py: search the devices for bluestore OSD
