Feature/673 xauth token

### Description
X-Auth-Token forwarded in notifications

Implements #673 
It should be like this in all tests ...
This test failed for me so I ran it manually. 10 times ...
After getting tired of setting the variable 'url' and 'payload', before calling orionCurl, I changed the names of the variables and I only had to do the call to curl once all variables were created.

It doesn't change the functest. Not at all. It just makes a little bit easier to do the test manually.
