#1033072 - Add indexes on package tables to improve performance with huge package sets

When hosting_package_instance hits > 150k rows, the code in hosting_package.instance.inc degrades really badly, yielding queries of 10-20 seconds and yielding to frontend requests of 1 to 5 minutes for the migrate dialog.

The indexes created here improves that performance notably, the queries going down to 0.1s and the requests down to < 10s.
