Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

```release-note
The main repository does not keep multiple releases of clientsets anymore. Please find previous releases at https://github.com/kubernetes/client-go

Pods which are evicted by the nodecontroller due to network
malfunction, or unresponsive kubelet should be differentiated
from termination initiated by other sources. The reason/message
are consumed by kubectl to provide a better summary using get/describe.
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.

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.
