Add 'Volume Type' lv_attr characters for RAID and RAID_IMAGE.
Add activation/retry_deactivation to lvm.conf to retry deactivation of an LV.

* FIXME: Get individual RAID image status.
* The status health characters reported from a RAID target
* indicate whether the whole array or just individual devices
* are in-sync. If the corresponding character for this image
* was 'A', we could report a more accurate status. This is
* especially so in the case of failures or rebuildings.
*
* We need to test the health characters anyway to report
* the correct 4th attr character. Just need to figure out
* where to put this functionality.
