 Description   

Found while testing fix for NETCONF-777.

Looks like exception mapper cannot serialize error response when module present on a mounted device is not present in the global schema context.

When deleting non-existent data on a device we should get a response like:

{
    "errors": {
        "error": [
            {
                "error-path": "/cars:cars",
                "error-type": "protocol",
                "error-tag": "data-missing",
                "error-message": "Data does not exist"
            }
        ]
    }
}

Instead we get a response with status 500 and an exception in karaf log that the error-path element cannot be serialized:

It looks like the json stream writer used in the exception mapper is using global schema context while serializing the path and if it doesnt contain the module from the device it fails.

This is actually a bit more complicated than it seems. The problem is really the fact the instance identifier is in the device scope, so really we should be reconstituting it to include the leading part, including yang-ext:mount, I think. The trouble with that is, of course, JSON/XML codecs do not support that sort of a mountpoint and probably do not integrate with InstanceIdentifier codec.

So this is error reporting of a well-known construct, which we need to be translating to an anydata value.
What RESTCONF should be doing here is creating a NormalizableAnydataNode, which is backed by whatever we have received from the device.
Once a conforming (JSON is not, I think) yang-data-codec-* hits this anydata node, it will invoke it with whatever EffectiveModelContext knowledge it has. When this happens, we should prepend the instance identifier with the DOMMountPoint identifier we have executed on, including the container where ext:mount is placed.
The second part of the trick is that the model which hosts yang-ext:mount must be enriched with an RFC8528 extension.
The finale is that when talking to the XML/JSON codec, we also supply it with a MountPointContext, which supplies the device's EffectiveModelContext when asked for a MountPoint.

With this, the identifier will be stitched without there being a yang-ext:mount-point thing in the picture.

The solution would be overly-complex. The document we are serving is a controller NB thing and the caller knows the mountpoint prefix – so they should supply that themselves.
If we were to prepend the paths, it would make it seem like we support operations across devices (i.e. YANG patch), when we do not.
