Handles for services that this component connects to.
connectTo: Handle<ConnectToInstance> | Handle<ConnectToInstance>;
The referenced service components must implement the ConnectToInstance interface. The Node Container will be started with the combined set of environment variables that are provided by all of the referenced components' connectEnv methods.
In case of environment variable naming conflicts among those in from the
connectTo prop, the value from the handle with the highest index in the
connectTo array will take precedence. In case of naming conflicts between
env, the value in
env will take precedence.
