Best Practice rule failures (evaluations?) need to generate events and be searchable.

[Alan-R]

See: https://trello.com/c/XRhZqwWu

• Events: One event should be generated for each new failure and each new success. Currently these events are ephemeral, but eventually will be persistent.
• Searchable. A relationship or node should exist for each failure, and maybe for each success. The general idea is that one should be able to easily search for all systems that failed tests, a total count of failures should be available, and it should be possible to collect the list of machines with any failure, or those which fail any given rule.

Dave's #19 commit addressed the first issue, but not the second. He'll get to that later...

This item is closed since the first part (generate events) is done. #25 comprises the second half (searchable) of this work item.
