text: Title: Custom test settings a.k.a. test metadata
  Body: It would be great If we have keyword that will be able to set `test metadata` to test report.  This is not issue, when you are running tests using robot, but when you're running tests using pabot the `suite metadata` is not enough to cover all the information that should be visible at the end of the run.
  
  Not mentioning that  rebot merge will mess  suite metadata  when they are added dynamically.
  
  
  I'm testing insurance systems and when i'm running tests I get a lot of different URLs where insurances are created. Each testcase have its own url and I'm looking for way how to `expose` that url in the report.
  For now I have custom keyword that logs this url to report, but it is not sufficient as you need to open test steps, open keyword and look for url there. So it should be really cool, if there are any  `test metadata`  that I can use to extract information and show them at on place in report
