Add logging middleware for more of the kolide Service interfaces.
This PR was created through code generation, however it's not likely that the logging middleware can all be continuously regenerated - we're likely to want to add method specific key/values to individual methods. Moving forward, logging middleware should be maintained when changes are made to a service interface method.
