VendContainer support for HouseArrest service

[jorgschulze73]

It appears that mobile_house_arrest binary supports command VendContainer besides the VendDocuments one that's already implemented in ios-deploy.

I assume it's used to query/access app containers so was wondering if it would be possible to add support for that as well?

Is there a need for supporting VendContainer? (e.g. what is the use-case you want to support)

VendContainer seems to work for dev-signed apps even without FileSharingUI enabled but otherwise seems to be mostly the same as VendDocuments. (not an expert, that's just what I gleaned from libimobiledevice/libimobiledevice#193)
