[FEATURE] [OAPIF provider] Add support for edition capabilities (OGC API Features Part 4)

[rouault]

• Issues OPTIONS on /collections/{coll_id} and collections/{coll_id}/{feature_id} endpoints to check server capabilities
• Add support for addFeature() through POST /collections/{coll_id} endpoint
• Add support for changeGeometryValues()/changeAttributeValues() through PUT /collections/{coll_id}/{feature_id} endpoint. Or through PATCH /collections/{coll_id}/{feature_id} with just the updated subset, if available
• Add support for deleteFeatures() through DELETE /collections/{coll_id}/{feature_id} endpoint.
• For POST/PUT/PATCH, takes into account Part 2 (CRS support) when implemented by the server.

Nice! We've made some testing and it works well. We experienced some quirks but we are quite sure they come from our backend for now.

@rouault I'm ok if you ignore some of the reviews suggestions -- this may not be performance sensitive enough to warrant the changes!

Hello,

I am testing with QGIS 3.34.1 and pg_featureserv CrunchyData/pg_featureserv#152
Features display correctly in QGIS, So the GET method works fine, unfortunatly QGIS does not seem to send OPTIONS calls sent to the backend.

Is there something I am missing ?
