func StartAndSyncInformer

func StartAndSyncInformer(ctx context.Context, informer cache.SharedIndexInformer) bool

StartAndSyncInformer starts the informer in a goroutine and waits until the initial cache sync is done. it returns a boolean that signals if the cache sync was successful.

Both the informer and the cache sync can be stopped by cancelling the provided context.
