As administrator, I'd like to have an API endpoint to list clusters of some other project in a region.
It would be something similar to /api/v1/clusters, but accepting OpenStack project id e.g. as path parameter /api/v1/{account}/clusters, and returning clusters of the project specified. Optionally, there could also be an endpoint returning all clusters in a region.
This might be useful when e.g. collecting resources of different projects using administrative user.
