Make microdep-map and microdep-ana only depend on reported test results (and no psconfig-files)

[ottojwittner]

Make analytic scripts (qstream-gap-ana.pl and trace_event_reader.py) as well as map-gui depend only on results reported by pscheduler and input to openseach, also for presenting measurement topology. No psconfig json input nor input from sqllight db should be required.

pschedule's ability to report all runs should be utilized to also present none-working measurement flows.

Support for output (optional) of topology events has been added to both gap analysis (qstream-gap-ana.pl) and traceroute analysis (trace_event_reader.py). The events are output regardless of status of tests reported by pscheduler, i.e. event "missed" and/or "failed" tests will result in topology events reporting to-from peers (with timestamps and geo-pos data).

The microdep-map is now also reading these events to plot test-nodes and measurement topology. There are still some bugs here though.
