Reset/delete catalog

Use this endpoint to reset/delete catalog for a branch.

This endpoint is ONLY meant to be used in case of data inconsistencies. Here is how you can carry this out in three steps:

1. Use this Delete API to reset/delete the catalog (calling this API will not immediately delete the catalog. Instead, the old catalog will ONLY be deleted when a new catalog request is sent with diff=false).
2. Push the entire catalog with diff=false.
3. If a catalog push request is in progress, then delete API would result in a 403 error code.
