Factor out lv info gathering function

The buildJsonReport function will soon have to perform the coupling of
instance data with LVInfo data. In preparation for that, in order to make
it more readable, the instructions for obtaining LVInfos are factored out...

Factor out the getInstances function

The getInstances function can be useful in general, but is defined inside
the InstStatus data collector. This commit takes it out and adds it to
a proper (newly created) library.

python code base earlier this quarter. We generalize the
name, because we needed a place for general storage...

Add a CLI parameter for input files

For many data collectors it is useful (especially for testing) to have to
possibility to specify an input file.

Add global status field to the instance status collector

The global status is computed from the statuses of the single instances.

The output json format is adapted to include this piece of information, as
prescribed by the design document.
