Ceph

I ran this as a test:

ceph-deploy osd prepare ceph01-osd02:sdb:/mnt/

And output is:

[ceph01-osd02][WARNIN] ceph-disk: Error: Journal /mnt/ is neither a block device nor regular file

It would be great if we could only provide a directory as journal, and when ceph-deploy detects this it would name the journal file as the OSD it creates in said directory.

After the above try I named the journal manually and got this output:

-4 2.71999     host ceph01-osd02
 2 2.71999         osd.2              up  1.00000          1.00000

which indicates the newly prepared drive is named osd.2 so ceph-deploy could name the journal /mnt/osd.2 when only applying
ceph-deploy osd prepare ceph01-osd02:sdb:/mnt/ instead of an error message which says Journal /mnt/ is neither a block device nor regular file.

It would make it alot easier and less of a pain to name the journal file if going with journal-file and not -dev with ceph-deploy.
