Add tests for jenkins agent check
Fix jenkins agent check when build does not yet have results
Refactor jenkins agent tests
Add build result as a tag to jenkins events
Add build number to tags for jenkins results
add logging of serverStatus errors

The current code does not check if db.serverStatus() returns an error (e.g. insufficient privileges). If that is the case, no message is logged anywhere, so user has no clue why metrics are not being posted. I propose to log a warning with the error message.
