Title: Edx/brianhw/include egginfo in packages

In order for packages that make use of entry points to work on a Hadoop node, the relevant egg-info directories also need to be copied to those nodes. This change performs a simple check to see if a related egg-info is present for a requested package, and adds those files as well.

For example, it will include the egg-info for the luigi package. With debug logging enabled, it will include:

```
