Add support for rendering >10k polygons #2233

Description

@gino-m

The web interface currently renders all polygons in the survey without any filtering or clustering. Clustering at lower zoom levels might help here, but the main bottleneck is loading the left hand panel. Let's put this in the queue for further investigation.

@jo-spek to provide related about the performance and issues with Android app.

    Duplicate of #1457. Kindly check and close one please @kenstershiro.

    A geolocation campaign in Nigeria has a survey with more than 10k polygons and using the web console is awfully slow.

    Clustering LOIs in the same fashion as in Ground Android may be the solution according to @rfontanarosa. Moving to P0 and current iteration at Roberto's request.

    Implementation in Ground Android:

    • Clustering on map
    • Lazy loading on scroll of list items
    • Slow load of selected LOI

    Lazy loading on scroll of list items - already released. Seems to have fixed much of the problem
