Job Evers-Meltzer 4334cdace1 Refactor blob requester to better seperate out the three requests
Each blob requests has three parts
- A request to see what blobs are available
- A request to download and pay for one of those blobs
- A request to negotiate data costs

Before the refactoring all of the code to accomplish this was mixed into
one class.  They are now three seperate classes.

There is still a lot of room for improvement, but it is at least better than
it was.
