Cloud policy now uses the ADT_PPAS field as the source but will only
take private PPAS due to requiring a fingerprint. If ADT_PPAS is empty
then the 'proposed' archive is used.
Adds logic to try and retrieve the install source of a package from the
logs. This is useful if multiple PPAs are defined since the policy won't
explicitly know when contains the package under test.
Changes made
- Multiple hardcoded fields moved to config
- Series is now retrieved from options
- Pocket is now called source and retrieved from config
- Adds source type config which can be either archive or ppa
- Returns REJECTED_PERMANENTLY policy verdict when test failures or
errors occur. Adds verdict info the the excuse.
The cloud policy is currently used to test whether the proposed
migration will break networking for an image in the Azure cloud. Cloud
testing will likely increase in scope in the future.
