A recent enhancement to MapStore2 has introduced dynamic WMS legends, which adapt the legend for a WMS layer to the content inside the map viewport.
This changes the previous behavior where legends were static.

Such a change introduces a few problems:

• projects where legends are expected always to show the full symbology
• increased rate of GetLegendGraphics requests that, in certain cases, can lead to performance issues (Regression in 4.4.2 : GetLegendGraphic requests timeout GeoNode/geonode-mapstore-client#2022)

We want to implement an option to revert to the previous behavior.

• The option can be set globally (localConfig) to affect the default behavior for legends.
• It can be overridden for a layer through Layer Settings

In my opinion, the default behavior should be the previous one, since this is what is expected normally, with the option to have dynamic legends.
