[RFC] Save custom geometries created with the SpatialFilter

[efernandezleon]

Target Use Case

A very common feature requested by customers in PS is the ability to create custom geometries to filter data and then, reuse those geometries later to apply the filters. Right now, the functionality of creating a custom geometry is built thanks to the FeatureSelectionLayer, but the shape is lost once the user removes it. This RFC exposes the need to provide the user the ability to save this shape with a name to be used in the following sessions.

Implementation Proposal

A possible implementation could be to assign a name to the geojson of the drawn shape and store in a remote component through a specific API. This API should provide the CRUD actions to operate with this entities.

Another possible implementation could be store those custom geometries in the local storage of the browser. The cons here is that you won't share these geometries with others users in the app, but the main pro is related to lack of a specific backend for this.

For me, this is a duplicate of #482 (comment).

The spatial filter should be treated as any other filter.
