Alert Rules do not have summary/description

Alert Rules do not have summary/description

Always

This bug is being raised by Openshift Monitoring team as part of effort to detect invalid Alert Rules in OCP.

Check details of following Alert Rules
1. KubeletHealthState
2. MCCDrainError
3. MCDPivotError
4. MCDRebootError
5. SystemMemoryExceedsReservation 

These Alert Rules do not have Summary/Description annotation, but have a 'message' annotation. OpenShift alerts must use 'description' -- consider renaming the annotation

Alerts should have Summary/Description annotation.

Alerts must have a summary/description annotation, please refer to style guide at https://github.com/openshift/enhancements/blob/master/enhancements/monitoring/alerting-consistency.md#style-guide 


To resolve the bug, 
- Rename message annotation to summary/description annotation
- Remove the exception in the origin test, added in PR https://github.com/openshift/origin/pull/27944
