Currently all outputs go in the user's home project which is undesirable due to the amount of clutter created.

Change this to create a new sub project under <user> / Workflow runs / <Workflow name + date of run> where all outputs are placed by default (unless the user specifies something different).

If a container request is submitted without an owner_uuid and without submitted_by_container_uuid, the API server creates a project for the the container request.

The container gets a new field, "runtime_project_uuid". This is set to the owner of the container request that created the container.

If a container request has "submitted_by_container_uuid", get the container and create the request under "runtime_project_uuid".

If the container in "submitted_by_container_uuid" doesn't exist (because it is federated container) then create a new project and create a stub container record with the remote container uuid and "runtime_project_uuid" set.
