Change event remediation w/o authentication
Currently, events remediated w/o authentication (ie no valid KCA presented by user) are placed in pending state.
This change will allow remediated events w/o authentication to be moved to the closed state. A check to look for 'repeat offenders' will be run for all events moved to the closed state. If a 'repeat offender' event is found, an RSS event will be triggered describing the 'repeat offender'.
A 'repeat offender' will be defined as a prior (within 90 days) closed event for the same system/issue.
