Reserved network locations for Studio and KDP

[bjester]

Summary

As a developer, in support of remote content browsing and pursuit of leveraging existing functionality, I would like to use the NetworkLocation models and associated architecture to interact with Studio and KDP. We can also leverage functionality added with the is_local attribute to generalize interacting with devices on the internet.

Note: KDP doesn't currently respond to the info endpoint, so we should prevent requests to KDP until we update KDP.

Deliverables

The task helper _enqueue_network_location_update_with_backoff

• It should prevent enqueuing new tasks when is_local is False

The model NetworkLocation

• A new type field should be added with choices of static, dynamic, and reserved
• A django migration should migrate all models with dynamic = False to have type of static (all dynamic = True can be deleted)
• The field dynamic should be removed from the model once type has been set
• The type field should be NOT NULL once migrated
• The existing DynamicNetworkLocation and StaticNetworkLocation models should be migrated to use the new type field

The task reset_connection_states

• It should update or create reserved network locations for Studio and KDP, using the URLs defined in Kolibri's options.ini
• The reserved network locations should use hardcoded IDs
• The connection state for the locations should be reset like static locations
• It should not enqueue a perform_network_location_update task for KDP, but should set its application to Kolibri Data Portal

The viewsets for NetworkLocations

• It should annotate a dynamic attribute on the response which is true when type is dynamic
• Only static models should be allowed to be created and it should set the type to static when creating them
• It should have a new syncable filter, which should include KDP's reserved location when 1 and Studio when 0
• If syncable filter is not provided, always exclude both KDP and Studio
• Its method update_connection_status should prevent making requests to KDP's location for the time being

Removed the following in favor of always excluding KDP and Studio from the response for the time being:

The composable useDevicesWithChannel

• It should send syncable=false to the viewset API

The composable useDevicesWithFacility and useDevicesForLearnOnlyDevice

• It should send syncable=true to the viewset API

Tagging #10765 as a reminder to implement a KDP availability check once implementation of this issue complete. It should be implemented independently.
