Use dedent for the kubectl commands

Browse Source 
The one side effect is that for the "kubectl help" commands a newline
is prepended to output, which will alter the yaml output.

Here we use dedent to format the code to match the output.

hack/update-generated-docs.sh has been run and the affected files have
been added.

Note: for describe.go we added a period to the end of an output message.

Expose a resource as a new Kubernetes service.
Looks up a deployment, service, replica set, replication controller or pod by name and uses the selector
for that resource as the selector for a new service on the specified port. A deployment or replica set
will be exposed as a service only if its selector is convertible to a selector that service supports,
i.e. when the selector contains only the matchLabels component. Note that if no port is specified via
--port and the exposed resource has multiple ports, all will be re-used by the new service. Also if no
labels are specified, the new service will re-use the labels from the resource it exposes.
