feat: Add mis build to the data factory

stocaaro commented 1 week ago

Problem

Users would like to use the Gen2 data client interface to access their APIs from application functions (lambda's).

Our docs offer instructions on this experience, which stop short of indicating how the customer should provide the model introspection schema needed to make the whole experience work.

Change

Build the Model Introspection Schema (MIS) in the data factory
Construct an S3 bucket with the MIS as an object
Grant get permission to the MIS to any function that is granted resource permissions to the data schema
Add the bucket name and object key for the MIS to SSM (where it will be read

In isolation, this change builds the MIS to S3 and grants permission, but the user story to consume this in a function would be complicated without the data config change that makes the in function configuration process trivial.

Validation

Unit tests added
Manually tested in an example application
Add E2E testing
