The work is being done here:
https://jira.opendaylight.org/browse/NETCONF-676
which looks like a duplicate of:
https://jira.opendaylight.org/browse/NETCONF-659
I think 676 might be covering a little more than 659, but at least for 659 it's easy to see
that the beirman GET on a notification subscription will have the location in the response
header:
{'Content-Length': '172', 'Content-Type': 'application/xml', 'Location': 'ws://10.30.170.68:8185/data-change-event-subscription/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE'}
whereas in rfc8040 test, its not there:
{'Content-Length': '178', 'Content-Type': 'application/xml'}
