Automated OSD HDD setup

There should be an optional attribute that allows you to specify that you want the osd's prepared automatically.

It should then allow you to specify a regex for the drives that should be automatically allocated (wholly) for OSD's. eg: [hvs]d[^a]

Based on this regex, the node's attributes should automatically be populated with the required structure as per the recipe:

"ceph": {

  "osd_devices": [

    { "device": "/dev/sdb" },

    { "device": "/dev/sdc" },

    { "device": "/dev/sdd" },

    { "device": "/dev/sde" },

    { "device": "/dev/sdf" }

  ]

}

This will be a good starting point - later it can be extended to allow automation for the way journaling is done and special attributes like dmcrypt.

Start by locating the Ceph OSD recipe and the node-attribute handling it uses; the issue provides no file or test names. Trace how the recipe currently consumes ceph.osd_devices, then define the optional preparation flag and drive regex behavior, with completion verified by the generated node structure and automated OSD setup.
