Enlistment preseed does not render full repository configuration

[Scott Hussey]

In MAAS 2.3.0, when nodes are enlisted the full repository configuration is not rendered in the preseed/clout-init data. The 'missing' piece is actually extra repositories if you have disabled pockets. During enlistment I see errors like the below even though I have disabled the security, updates and backports pockets for the Ubuntu archive. During commissioning and deployment, there are no issues with cloud-init managing repositories and packages.
