Add Job.GetAllBuilds() call

[Cidan]

It would be very useful to get all builds at once with one network call instead of one by one via GetBuild as it would make iteration of all builds many times faster.

You can get All build IDs that you can iterate with Job.GetAllBuildIds(), you will still have to make network request per build for more indepth data.

You can actually hit /view/All/job/<JOB_NAME>/api/json?depth=1 in order to get all build data in one call, which is what I'm referring to. It would make iterating over all jobs hundreds of times faster.
