Issue #141: synchronise polygons from BRMS to Forests

The PR does the following:

When a BRMS CFR that has a master polygon is updated, its NFA global id and polygon KML are added to the FMS queue for processing by a queue worker
When the queue item is processed the queue worker authenticates with the Forests system via the FMS API
Using the global id it makes a call to get the UUID of the corresponding CFR on forests.
When it has the UUID it then makes a patch call to update the CFR in Forests
