Add API endpoint for diff between two refs like GitHub and Bitbucket

[rafi]

GitHub allows base...head diff comparison in their API action /compare and appears in their go sdk as CompareCommits with base & head arguments.

Bitbucket has a similar API action /diffstat and appears in their go sdk as RepositoriesUsernameRepoSlugDiffstatSpecGet with a 'spec' argument for things like 3a8b42..9ff173.

It would be great if someone will able to add this feature. My current use-case is analyzing the change-sets on each commit in CI.

Yes please! Maybe also include this data in commit webhooks?

Make API "compare" accept commit IDs #32801

Does it resolve your issue?
