Added first draft of bonsai-alpha SDK

[mothran]

Adding a new bonsai top level directory to organize bonsai public crates into and added the bonsai-alpha / bonsai-serverless SDK as the first crate.

I added unit tests with a mocked REST api as well as a README with example usage and docstrings for all exposed methods. Currently the README docstring does not build and run because it pulls in a lot of deps that are:

• Coming in a pending PR: Publish Recursion Verifier #603
• Or not used anywhere else in the build, might make sense to make them dev-dependencies depending on if we just want a building but no_run example.
