Implement a script to approximate rebuilds by making sourceful uploads: POSTPONED

 * I don't understand how "Implement adding build records for successful builds" is different to the items below where you're requesting rebuilds. A build record has to exist before a build can start. -- Julian
   - Adding a second build record for successful builds. Currently they would only be created when there was a source but no binary. Retries would create new ones, but only where there was no previous successful builds. -- james_w
 * Adding build records en-masse is very slow, we've already got something in the pipeline to do this, the PackageCopyRequest table, which should be populated very quickly via an API request and then processed later in the background. -- Julian
    - That's for Launchpad, but these are workitems for an implementation in vostok. We may take a similar approach if we see the same things though. -- james_w
 * Do you mean no-change source uploads by "approximate rebuilds by making sourceful uploads"? -- Julian
   - Yes -- james_w
 * How else do you intend this to be different from COPY archives? -- Julian
   - Well it will be a different implementation. As for LP as far as I understand it COPY archives can't accept uploads. The spec talks about why we want to do more than COPY archives. If I'm wrong then it will be very easy to implement this spec in LP.
