and drop the now unused extract_lists function
this also fixes a bug, where we did not add the datastore to the list at
all when there was no rrd data

there is now a 'extract_cached_data' which just returns
the data of the specified field, and an api function that converts
a list of fields to the correct serde value
this way we do not have to create a serde value in rrd/cache.rs
(makes for a better interface)

this is an interface to simply get the Vec<Option<f64>> out of rrd
without going through serde values
we return a list of timestamps and a HashMap with the lists we could find
(otherwise it is not in the map)
if no lists could be extracted, the time list is also empty

disk_usage returned the same values as defined in StorageStatus,
so simply use that
with that we can replace the logic of the datastore status with that
function and also use it for root disk usage of the nodes
