Overly strict sanity check on post() method of DatasetCollectionHandler

[manor]

Given that it is now possible to post with ?host=datafile.root_domain, the test in line 2108:

        if self.request.uri != '/datasets':
           msg = "Method not Allowed: invalid datasets post request"
           log.info(msg)
           raise HTTPError(405, reason=msg)  # Method not allowed

is too strict since the suffix of the URI can legitimately be something other than /datasets...

Right, I need to review all the url checking code for PUT/DELETE/POST requests.

For now, can you work around this by just passing the host as the host header? E.g.:

        headers = {'host': 'datafile.root_domain'}
        payload = {'type': 'H5T_IEEE_F32LE', 'shape': 10}
        req = self.endpoint + "/datasets"
        rsp = requests.post(req, data=json.dumps(payload), headers=headers)
