NGSI10 Subscriptions with ServicePath

### Also not a PR

This 'failed test' comes complete with the logfile of the broker, and a description of the test (see the file SUBS_PATH), including contents in mongo after the test.

## Will NOT be merged, but discarded after discussion


You are missing two cases in the regex: "/a1/a2/a3/a4" and "/a1/a2/a3/a4/#".

Again, I'm not sure (yet now) if this a problem in the comment (that would need to be updated) or in the code (if the code is aligned with the current comment, the code should be fixed to include these 2 additional cases also)
