Displaying multiple metrics on the same map

[amotl]

Many people asked for supporting multiple metrics within the same map, mostly on https://github.com/grafana/worldmap-panel/issues/59.

• @Gelob, @polaton and @wainerthemainer asked for associating different metrics with different colors. See also https://github.com/grafana/worldmap-panel/issues/28, https://github.com/grafana/worldmap-panel/issues/230 and https://github.com/grafana/worldmap-panel/issues/246.
• @drzhouq asked to support multiple metrics. He wants to show both wind speed and temperature for the same location.
• @stewba suggested to use different shapes (circle, square, triangle or similar) to tell different measurements apart. See also #23.
• @diamondo25 suggested to optionally choose one metric for the coloring/ring size and the others to be shown in the tooltip. See also #28.
• @Alex-Smart asked about how to show green dots/circles for successful requests to a server (i.e. 200 code) and red ones for failed requests on the map.
• @robynhub would like to mix GPS data on one measurement with signal levels on another.

  I think this is very common for people using WorldMap Plugin and InfluxDB on LoRa coverage mapping applications.

• @falconhome also asked for this. See also https://github.com/grafana/worldmap-panel/issues/279.

  I need to visualize two different datasource query in one map. The first one is come from MySQL source (lat, lon, name, metric - static master datas). The second measurement from InfluxDB (with same lat, lon, name, metric our nodes datas).

We love worlmap panel, Adding support for multiple metrics and also controlling the unit of those metrics will be extremely helpful

@amotl - anything you can help us on this one ?

+1 not sure best way of how to request/suggest but customer shapes (polygon or multipolygon) say by receiving WKT from MySQL would be such a powerful feature
