As system, I should be able to link and unlink existing defects to test run steps using the REST API

As system, similarly to what is possible to do at the testrun level, it should also be possible to link and unlink existing defects to test run steps using the REST API.

PUT api/testrun/

/step/

/

{
    "defects": {
        "add": [
            "CALC-1",
            "CALC-2"
        ],
        "remove": [
            "CALC-3"
        ]
   }
}
