LAD mdsd .deb and .rpm packages should include triggers to restart mdsd if the OMI package is updated

If the OMI package is updated while mdsd is running, and if the OMI update includes a breaking protocol change between the OMI client SDK and OMI server, then the running mdsd will be using the old client library to try to talk to the new server, and that won't work. A package trigger should be added which restarts the mdsd service (if and only if it's running) when the OMI package is updated.
