by moving the properties of the storage status out again to the top
level object
also introduce proper structs for the types used, to get type-safety
and better documentation for the api calls
this changes the backup counts from an array of [groups,snapshots] to
an object/struct with { groups, snapshots } and include 'other' types
(though we do not have any at this moment)
this way it is better documented
this also adapts the ui code to cope with the api changes
