Better Error Message on Fieldnames; Add start_container
## Changes Title (replace this with a logical title for your changes)
### Description
This PR extends the Rancher Driver to add `start_container` support. It
follows the base class so providing a container object is necessary (and you
get one back as expected).
Additionally, I ran into an a scenario where fields which caused errors
would return something like:
```
In [12]: driver.ex_deploy_service(name='empty_test', image=image,
environment_id="", service_description="testing",
environment={"ohnoes":"maybe"})
---------------------------------------------------------------------------
BaseHTTPError Traceback (most recent call last)
<ipython-input-12-e9850d5a4dbf> in <module>()
----> 1 driver.ex_deploy_service(name='empty_test', image=image,
environment_id="", service_description="testing",
environment={"ohnoes":"maybe"})
/home/mloria/arrovenv/libcloud/libcloud/container/drivers/rancher.py in
ex_deploy_service(self, name, image, environment_id, start,
assign_service_ip_address, service_description, external_i
d, metadata, retain_ip, scale, scale_policy, secondary_launch_configs,
selector_container, selector_link, vip, **launch_conf)
394 data = json.dumps(dict((k, v) for (k, v) in
service_payload.items()
395 if v is not None))
--> 396 result = self.connection.request('%s/services' %
self.baseuri,
397 data=data,
method='POST').object
398
/home/mloria/arrovenv/libcloud/libcloud/common/base.py in request(self,
action, params, data, headers, method, raw)
860
861 try:
--> 862 response = responseCls(**kwargs)
863 finally:
864 # Always reset the context after the request has
completed
/home/mloria/arrovenv/libcloud/libcloud/common/base.py in __init__(self,
response, connection)
177 raise exception_from_message(code=self.status,
178 message=self.parse_error(),
--> 179 headers=self.headers)
180
181 self.object = self.parse_body()
BaseHTTPError: None - None
```
So I edited `parse_error` to check for this and print something a bit nicer:
```
BaseHTTPError: name is NotUnique: None - None
```
