RPM Support

Description of problem:
The RPM unit type JSON file specifies the first field of the unit key as a search index on multiple types[0]. For example, RPM lists "name" as a search index and also as the first element of the unit key. This is redundant since the unit key causes a uniqueness constraint on the collection that effectively gives us a free "name" index. The harm in doing this is that MongoDB will use more RAM and will make writes slower since it has to update two indices needlessly.

Version-Release number of selected component (if applicable):
2.4.3-1

How reproducible:
Every time.

Steps to Reproduce:
1. Look at /usr/lib/pulp/plugins/types/rpm_support.json

or

1. Use Mongo's shell to inspect the installed indices on the various unit collections.

Actual results:
There are redundant search indices.

Expected results:
There should not be any redundant search indices.
