Generate and deploy extensions

[amcaplan]

WHY are these changes introduced?

Related to https://github.com/Shopify/develop-app-management/issues/1757 Fixes https://github.com/Shopify/develop-app-management/issues/1710

WHAT is this pull request doing?

Allows generating and deploying extensions. Includes:

• Fetching extension specifications
• Stub-out of template specifications (those will be addressed in a later PR)
• Filling in UIDs in module TOMLs, and reading them for future deploys
• Matching local and remote modules via UID
• Pushing an extension bundle to cloud storage

(Generating a version already existed, now it'll work with extensions as well.)

Functions aren't expected to work yet, as uploading those artifacts is a bit different.

How to test your changes?

1. Create an app
2. shopify app generate extension (generate a few kinds, but no functions)
3. shopify app deploy (confirm the diff looks correct)
4. shopify app deploy again (confirm the diff shows no changes)
5. Generate another extension, and deploy again (confirm the diff shows changes appropriately)
6. Confirm that all extensions TOMLs have UIDs
