Adding statscompanion_service and a dontaudit for find/add

Instead of removing the denial generating code, a dontaudit and a
service label will be provided so that the team working on this new
feature doesn't have to get slowed up with local revision patches.

The dontaudit should be removed upon resolution of the linked bug.
