Code Issues Proposed changes

Allow operators to use 'fallback mode' for Ceph disks

Browse Source 
This change adds a variable to the Ceph role "kolla_ceph_use_udev",
which is True by default meaning no change to the current behaviour. If
set to False, it will fallback to tools such as sgdisk/blkid to parse
the disk info it needs, instead of using udev.

features:
- Add a new variable for the Ceph role, 'kolla_ceph_use_udev',
which when set to 'False' relies on system tools such as
sgdisk/blkid to read the necessary disk info required
to bootstrap Ceph disks on older systems. Most operators
should not need to change this.
