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.

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

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.

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

ae2f6a833a Reduce volume of logs generated at v(3) 
Node controller is generating a huge amount of logging at v(3) that is
more appropriate for v(5). Split the log into two levels and ensure it
also ends up on one line (so grep works).

The pod manager generates a v(4) pod output on sync that always contains
a newline - since the size of the pod is so excessive in output, kick it
to v(5) for deep debugging (we're pretty happy with this loop).

We will have the rigth formula to generate correct maxCIDRs now.
Previous code assume cluster CIDR is /8 which may not be true.
Now it generates maxCIDR based on the info of cluster IP.

3928bd6e76 Fix TODO in pkg/controller/nodecontroller.go line 472 
The code now calculates and find out the CIDRs for every node in any sync period.
I will fix this TODO by maintaining a set for available CIDRs left. Firstly, I will
insert 256 CIDRs into the available set. Once someone get one CIDR, remove this CIDR
from the available set. If one node get deleted, we will reinsert the CIDR associates
with this node back to available CIDR. Once there are nothing left in available CIDR set,
generate another 256 CIDRs and insert them into the available set. As a result, we do not
need to generate CIDRs in every monitor process and we only need to assign CIDR to node
which does not have it.

This commit also fix the error that CIDR may overflow when we use the function
generateCIDRs. There will be no more ip overflowing, all assigan CIDR will be valid
