Should have an upsert method supporting natural keys

[thgreasi]

We can implement a method even before pine support for this is added, but doing a POST and if it fails change it to an PATCH with the natural key props as a filter.

pine.upsert({
	resource: 'device_tag',
	id: {
		device: deviceId,
		tag_key: 'testTag',
	},
	body: {
		value: 'testValue',
	},
});

Eventually when pine supports this, the OData query might look like:

PUT /device_env_var(device=$device,tag_key=$tag_key) {value: '$value'}
