v2.0.0rc4

Catalog

• The defaulting of the namespace value for Blobs has changed slightly. If no namespace is specified,
  it will default to <org>:<hash> with the user's org name and unique user hash. Otherwise, any other value,
  as before, will be prefixed with the user's org name if it isn't already so.
• Blob.get no longer requires a full id. Alternatively, you can give it a name and optionally a namespace
  and a storage_type, and it will retrieve the Blob.
• Fixed a bug causing summaries of Blob searches to fail.

Compute

• Function.map and Function.rerun now save the created Jobs before returning.
• Job.get return values fixed, and removed an extraneous debug print.

General

• Updated requirements to avoid urllib3>=2.0.0 which break all kinds of things.
