Dominik Csapak ec8f042459 api2/status: use new rrd::extract_cached_data
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

Dominik Csapak 431cc7b185 rrd: move creation of serde value into api
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)

Dominik Csapak 6cad8ce4ce rrd: add 'extract_lists'
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
