More robust error reporting/handling for DM errors, new RESTful function: odareset

Use odareset to delete all data in the ODA server associated with a scenario and to
reset the ingestion engine's store of what was downloaded for the scneario, but keep
the scneario definition.  Acssible via the REST inteface:
   http://<server>:<port>/ingest/ManageScenario/odareset/<scid>,
scid is the ncn_id of the scenario.
Example:
  http://127.0.0.1:8000/ingest/ManageScenario/odareset/scid_01
