Chris Holcombe a8790f2303 Add support for replacing a failed OSD drive
This patch adds an action to replace a hard drive for an particular
osd server.  The user executing the action will give the OSD number
and also the device name of the replacement drive.  The rest is
taken care of by the action. The action will attempt to go through
all the osd removal steps for the failed drive.  It will force
unmount the drive and if that fails it will lazy unmount the drive.
This force and then lazy pattern comes from experience with dead
hard drives not behaving nicely with umount.
