[BZ 1158892] Remove AllEndpointStates property of FailureDetector service from the plugin descriptor. This will prevent a high curn of configuration changes for the service due to the ever changing nature of the property. The property is not needed at this point by any functionality in the Cassandra or Storage Node plugins.
