// SetEnvsToApp adds environment variables to an app, serializing the resulting

// parameters: publicOnly indicates whether only public variables can be
// overridden (if set to false, setEnvsToApp may override a private variable).
//
// If useQueue is true, it will use a queue to write the environment variables
// in the units of the app.
