Map layers render slow because we are using direct wms request

[NyakudyaA]

Problem

In the map layer request, we are using direct wms request, we need to utilize the full capability of Geoserver caching so that map layers are rendered fast.

Example http://testing.healthyrivers.kartoza.com/bims_proxy/https://maps.kartoza.com/geoserver/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&layers=kartoza:cba_national_mview&format=image/png&WIDTH=256&HEIGHT=256&CRS=EPSG:3857&STYLES=&BBOX=2661231.576776698,-3757032.814272985,2817774.610704739,-3600489.780344944

We should add the following to the request. tiled=true This will ensure that request is fetched from the cache and if not they will be fetched from wms but then cached.

cc @dimasciput @timlinux I think this will improve the user experience for rendering map layers in the front end
