Bitrise API - Filter builds by commit_hash

Description of the feature request

I’d like to be able to filter builds on the Bitrise API by the commit hash of the build.

This could be supported with a query parameter e.g.

&commit_hash=abcdefgh

This would be useful on the following endpoints
GET /apps/{app-slug}/builds
GET /builds

Use case / for what or how I would use it

This would be useful to determine if any builds have been triggered for the specific commit hash.
