type EndpointReconciler 

type EndpointReconciler interface {
	// ReconcileEndpoints sets the endpoints for the given apiserver service (ro or rw).
	// ReconcileEndpoints expects that the endpoints objects it manages will all be
	// managed only by ReconcileEndpoints; therefore, to understand this, you need only
	// understand the requirements.
	//
	// Requirements:
	//  * All apiservers MUST use the same ports for their {rw, ro} services.
	//  * All apiservers MUST use ReconcileEndpoints and only ReconcileEndpoints to manage the
	//      endpoints for their {rw, ro} services.
	//  * ReconcileEndpoints is called periodically from all apiservers.

http://<host>/apis/company.com/v1/foos/...
