Title: import novaclient.exceptions for cs.images.find

`cs.images.find(human_id=` throws novaclient.exceptions.NotFound, resulting in the try/except block with
`image = cs.images.find(name=image)` being skipped. catching novaclient.exception.NotFound allows images to be specified with the human readable name.

Example:
```
tasks:
- name: Server build request
local_action:
module: rax
region: DFW
image: Ubuntu 12.04 LTS (Precise Pangolin)
```
Also, the import is placed after try: import pyrax, because pyrax
imports novaclient and should fail if novaclient is missing.
