org.rhq.core.pluginapi.operation.OperationFacet
This facet must be implemented by resource components that want to expose one or more operations.

            // create our timer task that will force the operation invocation to time out if it takes too long to complete
            final long operationTimeout = getOperationTimeout(operationDefinition, parameterConfig);


            // ensure the facet method timeout is comfortably longer than the operation timeout
            long facetMethodTimeout = operationTimeout + (10 * 1000L);
            final OperationFacet operationComponent = getOperationFacet(resourceId, facetMethodTimeout);
            final TimerTask timerTask = new TimerTask() {
                // TIMER TASK THREAD - waits until the timeout time expires - if this is not canceled before the timeout hits,
                // the operation invocation thread is interrupted and the server will be told the operation has timed out.
