feat: grow support for fluxion

This changeset exposes the (WIP) API to allow a resource
graph to grow, which needs to be a call to the c api
"grow" that gets passed to unpack_at. This is a WIP
because the container build has a custom clone/build of
flux-sched with the grow-api branch, and we will need
to eventually update that.
