lazr.restful needs to be imported on staging/production

[Anthony Lenton]

For some reason specific to our staging/production environments, you need to import lazr.restful as a first step in any script for it to work. Otherwise it fails with a traceback very similar to this:

{{{
sca@dysprosium:/srv/sc.staging.ubuntu.com/staging/code/framework$ python migrate-departments.py
Traceback (most recent call last):
  File "migrate-departments.py", line 14, in <module>
    from softwarecenteragent.models import Department, Application
  File "/usr/lib/python2.6/dist-packages/softwarecenteragent/models/__init__.py", line 1, in <module>
    from .webservice import (
  File "/usr/lib/python2.6/dist-packages/softwarecenteragent/models/webservice.py", line 25, in <module>
    from softwarecenteragent.subscription_states import (
  File "/usr/lib/python2.6/dist-packages/softwarecenteragent/subscription_states.py", line 14, in <module>
    from softwarecenteragent.utilities import (
  File "/usr/lib/python2.6/dist-packages/softwarecenteragent/utilities.py", line 13, in <module>
    from launchpadlib.launchpad import Launchpad
  File "/usr/lib/pymodules/python2.6/launchpadlib/launchpad.py", line 28, in <module>
    from lazr.uri import URI
ImportError: No module named uri
}}}

That is, it fails to find lazr.uri. Funnily, importing lazr.restful at the top of the script you're attempting to run fixes this issue.

This may go away with the precise upgrade. This will need reviewing again then.

[Tong Shinn (tshinn)]

This has most likely been resolved, based on the following observations:
- subscription_states.py no longer imports from softwarecenteragent.utilities
- softwarecenteragent.utilities no longer exists and cannot be imported
- launchpadlib.launchpad no longer exists and cannot be imported
