Allow setting storage mappings for OVA disks

[mansam]

• Exposes OVA appliance disks as mappable storage in the OVA inventory collector.
• Permits mapping any or all OVA appliance disks to their own destination storage classes.
• This requires a UI change in order to list the source disks in the storage mapping creation view properly. This case needs to be replaced with code similar to the other providers to list the source storage (disks) belonging to the selected VMs.

Implements #1213

Note: Please ignore default mapping in below screenshots, the default mapping has been removed.
