SCOM - Duplicate Signature ID usage detected for STT Signature ID

1. The HealthService starts the new rules in the configuration 
2. The STT module starts up attempts to register the signature id and 
    cannot since another version of the same rule is running. 
    The module then logs the event and unloads the workflow. 
3. The HealthService stops any old rules not in the configuration. 
4. The old version of the rule is stopped hence the duplicate signature id 
   is unregistered. 
5. The HealthService reloads any rules which failed during step 1. 
6. The STT module starts up normally (no issues registering the duplicate id)
