3761	Fake client/server pair implementing proposed GBS Python interface (part 1: immutables)	itamarst	itamarst	"In order to refactor the Tahoe-LAFS client code to support two protocols in parallel, we need some implementation of a new low-level client storage Python interface (let's call it `IStorageClient`). The production `IStorageClient` implementation will talk the GBS HTTP protocol to the storage server.

However, since the wire protocol is going to have to be audited, and since having a (verified) fake implementation is useful for writing more isolated tests, a useful first step would be a `IStorageClient` implementation that is implemented in-process.

The deliverables for this will be:

1. A new interface, `IStorageClient`, corresponding the the proposed HTTP protocol.
2. A compliance test suite for `IStorageClient` providers.
3. A (verified) fake `IStorageClient`. Since it won't talk over the network, there is no need for a separate server.

It will be limited to immutables, with mutables in a follow-up ticket."	task	new	normal	HTTP Storage Protocol	unknown	n/a
