Justin Santa Barbara 54195d590f Use strongly-typed types.NodeName for a node name 
We had another bug where we confused the hostname with the NodeName.

To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.

A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName

Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.

Sleep between NodeStatus update retries

Just a thing I found when looking into other problems.

This is pretty much no-risk change fixing wrong behavior. Do you think it should go in 1.4? @pwittrock

Xing Zhou 46c302b4c2 Used goroutine to launch node controller's internalPodInformer. 
Node controller's internalPodInformer will block main thread
if it is not started as a go routine. This patch fixed this
by runing internalPodInformer as a go routine.

to embed `sync.Mutex` into parent structs.

k8s-merge-robot 577cdf937d Merge pull request #26415 from wojtek-t/network_not_ready 
Automatic merge from submit-queue

Add a NodeCondition "NetworkUnavaiable" to prevent scheduling onto a node until the routes have been created 

This is new version of #26267 (based on top of that one).

The new workflow is:
- we have an "NetworkNotReady" condition
- Kubelet when it creates a node, it sets it to "true"
- RouteController will set it to "false" when the route is created
- Scheduler is scheduling only on nodes that doesn't have "NetworkNotReady ==true" condition
