Read the rest of the mesh and the network over mesh-sdk, and fail when a caller reaches for the old composition (issue 1388)

The seats, holdings, source, build-source, delivery group check, check request, backup plan, adoption (take and converge) and the network graph now read the rest of the mesh through restOfTheMesh and compose.Graph. compose_callers_test.go scans the package and names any function other than the old composition's own that still calls planFor, declarationWith, composedAndValidated, generators, renderingFor, theRestOfTheMesh or whoResolves; issue 1389 deletes those.
