There is a chance when ceilometer-agent-central try to trigger interval_task but keystone is not available, then an exception is raised but not caught, the outside oslo.loopingcall will stop calling the task function, finally leading to the agent-central service is no longer available forever, even the keystone is available again. We can skip the particular interval_task when keystone is not available. Change-Id: I0849cafadac8fb8a7670aaa4cc76dc708bdb25a1 Closes-Bug: #1287613
