Restart Service Monitor Service on deployment

I've noticed that on occasion the New Relic Server Monitor service stops running after a deployment. While the upgrade to a new version is successful, I have to remote into the cloud service and start the service manually. This can be a frustrating experience, especially if I don't have remote desktop enabled for the cloud service.

This pull request restarts the service automatically. I tested this on a couple different cloud services where the Server Monitor was no longer running and it successfully brought the monitor back up.
