In the CI tests dashboard add a new optional column to report the warning/failure reason for CI tests
When an CI test fails or reports warning it reports also the reason.
This is feature is already available for the skipped CI tests.
For the users it is useful to get the warning/failure mode directly form the CI test dashboard.
This warning/failure reason will be passed through the "statisticname" attribute named "warning_reason" or "failure_reason" respectively.
The "value" attribute will report the actual "reason".
The valuetype will be set to "string".
