Most of our communications from apiserver -> nodes used
nodutil.GetNodeHostIP, but a few places didn't - and this
meant that the node name needed to be resolvable _and_ we needed
to populate valid IP addresses.
Fix the last few places that used the NodeName.

KubeletClient implements ConnectionInfoGetter, but it is not a complete
implementation: it does not set the kubelet port from the node record,
for example.
By renaming the method so that it does not implement the interface, we
are able to cleanly see where the "raw" GetConnectionInfo is used (it is
correct) and also have go type-checking enforce this for us.

Use strongly-typed types.NodeName for a node name
We had another bug where we confused the hostname with the NodeName.
Also, if we want to use different values for the Node.Name (which is
an important step for making installation easier), we need to keep
better control over this.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName

Move Kubelet pod-management code into kubelet_pods.go
Finish the kubelet code moves started during the 1.3 dev cycle -- move pod management code into a file called `kubelet_pods.go`.
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.

Variables should be initialized near where it would be used
As inner the for-loop, it would continue before hash-value being used, so i thinks the hash value calculation should be moved below

CRI: add Message in ContainerStatus
Kubernetes expects a brief CamelCase string as "Reason" and a human-readable
string as "Message" in the conatiner status. It is difficult for kubelet to
derive the other one if the runtime only provides one of the two fields.
Augment the API by adding the "Message" field.

Add positive logging for GC events
We have no positive logging for GC events. This PR:
1. Adds positive logging at V(4) for success cases
2. Adds positive logging at V(1) for the first successful GC after a failure

Fake container exec/logs support for in-process docker CRI integration
This is necessary to unblock other work on docker integration, while we are addressing
`logs` and `exec` in the meantime.
This is part of #31459 and #33189
/cc @kubernetes/sig-node
This is a temporary hack to bypass CRI when getting container logs or
running exec in a container. This is necessary to unblock testing and adding
other features in the integration.

Move image pull throttling logic to pkg/kubelet/images
This is part of #31458
This allows runtimes in different packages (dockertools, rkt, kuberuntime) to
share the same logic. Before this change, only dockertools support this
feature. Now all three packages support image pull throttling.
