CLI - Add (back) support for project config files

[bfops]

Background

We used to support project-specific config files (similar to a project-specific git config). We removed support for these, but we'd like to add it back eventually.

Definition of Done

TODO

• (Default) server to publish to
• (Default) database name to publish
• (Default) build options
• Still WIP

[jsdt]

It would also be helpful if a project file had:

1. The location of the module (which might be part of what you mean by build options)
2. The location where client SDKs should be generated

Design work, at least, is dev ex.
