OpenShift must configure Alert Manger Receivers to notify SA and ISSO of all audit failure events requiring real-time alerts.

Description
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less). Satisfies: SRG-APP-000360-CTR-000815, SRG-APP-000474-CTR-001180
