As a machine, the REST API should return a list of Test Runs based on given parameters

The REST API should provide an endpoint for obtaining a list of Test Runs based on some parameters (one of them must be specified):

• testExecutionKey
• testPlanKey
• id of saved filter (for filtering Test Executions)
• (optionally) testKey

It should be possible to enumerate a list of Test related fields that should be returned for each Test Run's Test information, using the parameter includeTestFields=field1,field2,...,fieldN

GET /rest/raven/1.0/testruns

Each testrun in the response should provide also the Test Run's id and also the Test Execution key.
 
E.g.:
...
      "id":1587,
      "testExecKey":"CALC-13"
 
Note: The current endpoint for exporting test results should be deprecated (http://confluence.xpand-addons.com/display/XRAY/Export+Execution+Results+-+REST). In fact, it should now be an alias to the new endpoint.
