Description of problem: Today the watchman plugin source is stored under /etc/openshift/watchman and owned by the openshift-origin-node-util package. This is a problem for administrators that might want to selectively enable or disable plugins. Updating the package can undo their preferences. Instead the plugin source should be stored elsewhere and perhaps symlink'd into the drop directory. Somewhere under /usr/share would probably be appropriate. Another alternative would be something similar to how the plugins under /etc/openshift/plugins.d are auto loaded by the broker.
