Rework to run against Blobstore

[MrCreosote]

Should be mostly similar, but needs renames across the board and to be tested against blobstore.
Probably makes sense to make a new repo

[MrCreosote]

Note should return the blobstore version vs. the shock version

[MrCreosote]

Or just use a REST client like Jersey. Not sure if the blobstore really needs a client
