Bug 805192

Because this is RHUI and no one has yet migrated past version 35, we can modify migration version 35 directly.  This will make it so that we can add the needed indexes and rewrite the slow part of the migration to be much more efficient.

We can do these same changes in pulp, but we need an additional migration (version 39) to add the indexes.

We can then also pull migration 39 back into rhui so that the 2 branches stay on the same db version.  version 39 will essentially be a no-op in the rhui branch since the indexes were already added as part of 35.

commits 493dcab291438644bb8c433de9254acfbcef5245 and feddbea87e443e55175fdb3d4095120e97beba31 in pulp rhui branch

QA:
the pulp-migrate command during the update process should run quicker than it did before.  Previously, on a RHUI with all of RHEL 5 and RHEL 6 sync'd and a few layered products, it was taking at least 2 hours.  It should now take closer to 45 minutes.

If you don't have a good way to test this, then just verifying that the update process works is sufficient.

Upgrade both from 2.0.1 and 2.0.2 works well.

F: The pulp-migrate command was re-written to be nore efficient on RHUI systems with many errata.
R: RHUI systems with Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and some layered products installed and updated, should now take around forty-five minutes to perform the update process with pulp-migrate.
