update `kubectl expose` output to UsageError

**Release note**:
```release-note
NONE
```

This patch updates `kubectl expose` output (with no resources provided)
to a UsageError so that the `kubectl expose -h` suggestion is displayed.

##### Before
`$ kubectl expose`
```
error: You must provide one or more resources by argument or filename.
Example resource specifications include:
   '-f rsrc.yaml'
   '--filename=rsrc.json'
   'pods my-pod'
   'services'
```

##### After
```
error: You must provide one or more resources by argument or filename.
Example resource specifications include:
   '-f rsrc.yaml'
   '--filename=rsrc.json'
   'pods my-pod'
   'services'
See 'kubectl expose -h' for help and examples.
```
