NewManager returns a new manager to manage all the controllers

func (*Manager) Run

func (c *Manager) Run(ctx context.Context, rolloutThreadiness, serviceThreadiness, ingressThreadiness, experimentThreadiness, analysisThreadiness int, electOpts *LeaderElectionOptions) error

Run will sync informer caches and start controllers. It will block until stopCh is closed, at which point it will shutdown the workqueue and wait for controllers to finish processing their current work items.
