Add support for excluding logicaldrive

[pavoldomin]

I want to exclude smart array logicaldrive recreation; placed this in config:

# grep logical /etc/rear/site.conf
EXCLUDE_RECREATE=( fs:/backup logicaldrive:/dev/cciss/c0d0 logicaldrive:cciss/c0d0 )


# rear -D -v savelayout
Relax and Recover 0.0.810 / 2012-03-16 18:37:24 +0100    
Creating disk layout
Excluding RAID md2. 
Excluding Volume Group lvlocal
Excluding Volume Group vgbackup
Excluding component fs:/backup
Excluding component logicaldrive:/dev/cciss/c0d0
Excluding component logicaldrive:cciss/c0d0
Finished in 20 seconds

However, it's still included in disklayout:

# grep c0d0 /var/lib/rear/layout/disklayout.conf
# disk /dev/cciss/c0d0 146778685440 msdos
# part /dev/cciss/c0d0 213057536 16384 primary none /dev/cciss/c0d0p1
# part /dev/cciss/c0d0 146565611520 213073920 primary none /dev/cciss/c0d0p2
# lvmdev /dev/lvlocal /dev/cciss/c0d0p2 XelE5V-1QBS-QbUV-8APC-m3UY-Y55t-ElRQ7W 286260960
logicaldrive /dev/cciss/c0d0 0|A|1 raid=1 drives=1I:1:1,1I:1:2, spares= sectors=32 stripesize=

Logical drives are currently not tracked in disktodo.conf or diskdeps.conf. We will have to add them before exclusions will start working.
