Display more metadata for ESRI layer

[naoliv]

While reading ​https://github.com/Esri/arcgis-osm-editor/issues/104#issuecomment-347296365 I saw that iD is able to display some informations about the ESRI imagery layer, like this:

Could we also have this when we right-click and then select Show tile info?

Did I just saw an ESRI employee create a pull request to iD? Waw. We have to lobby them so that they create JOSM patches too.

For Bing the metadata is quite simple to obtain, we just look at this HTTP header:

        String str = urlConn.getHeaderField("X-VE-TILEMETA-CaptureDatesRange");
        if (str != null) {
            tile.putValue("capture-date", str);
        }

For ESRI it requires to call a REST API, it needs a JMapViewer evolution.
