Move ordering logic out of AbstractSubtreeManagerRegistryBuilderBuilder
Introduces YangDAG that maintains topological order for yang schema nodes and can be used by other components to read additional graph edges, e.g. from file (HONEYCOMB-365). Change-Id: Ia3046d38ffb4ca222412309f6c4391afc9315bd2 Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
