(Enhacement) Partition.subvolumes gives incomplete information

[wllacer]

Partition subvolumes returns only mounted subvolumes. It should also return information from subvolumes defined but not mounted. Two problems to implement it.

• btrfs (the utility) has/haven't found no output mode prepared for script output, so its results have to be parsed by hand
• To get the list of subvolumes you need the btrfs filesystem root mounted (can be done in parallel to real mount)

• This issue is rather an enhacement request, as AFAIK no current code needs it (but i will for the new disk manager). Not a high priority for me right now; so, if anyone wants to step into ...

Update MapperDev has also the same code

I'll take a look, building a parser should be easy enough
