------------------------------------

             Summary: Introduce result status TEMP_UNAVAILABLE for health checks
                 Key: FELIX-6005
                 URL: https://issues.apache.org/jira/browse/FELIX-6005
             Project: Felix
          Issue Type: Improvement
          Components: Health Checks
            Reporter: Georg Henzler
            Assignee: Georg Henzler


Currently, health checks support the following result status values:
{code}
OK -> System usable
WARN -> System usable, tendency to CRITICAL (action needed to avoid this)
CRITICAL -> System not available
HEALTH_CHECK_ERROR -> Error while trying to get a status 
{code}

In addition to that there should be a status
{code}
TEMP_UNAVAILABLE -> System not available, tendency to OK
{code}
 
See [1] for a more detailed table (DRAFT version)

This new status is similar as "Red/Amber" for traffic lights [2] (and hence AMBER is ambiguous it's better to stick with OK/WARN/CRITICAL for now instead of traffic light colors)

The table should be taken over to [3] in order to make all SPI implementors aware of the expectation their result status will come with.
