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.

Fix FakeNodeHandler Update behaviour
Two problems:
1. Get is always using Existing nodes slice, and you will for sure miss any updated data
2. Each Update adds a duplicate node entry to UpdatedNodes slice
For the 1st, we will try to find a node in UpdatedNodes slice (same as for the List).
2nd - append only if there is no node with same name as updated, if there is we will replace object in UpdatedNodes slice.

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
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.

Node controller deletePod return true if there are pods pending deletion
Fixes https://github.com/kubernetes/kubernetes/issues/30536
If a node had a single pod in terminating state, and that node no longer reported healthy, the pod was never deleted by the node controller because it believed there were no pods remaining.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.
