Post-hashstore Refactor

[artntek]

The indexer currently uses a node token to get non-public system metadata through DataONE api.

After the system has been changed to use hashstore, this will no longer be necessary, since metadata can be accessed directly from the store.

The following changes will therefore be required, when hashstore is up and running:

• refactor the code to get metadata directly from hashstore (obviously :-)
• remove the config that currently provides the metacat/dataone api url, including:
  • index.d1node.baseURL in helm/config/dataone-indexer.properties
  • definition of "idxworker.mn.url" from helm/templates/_helpers.tpl, plus any of its other uses
  • The following from helm/templates/deployment.yaml:

          env:
            - name: DEBUG
              value: "{{ .Values.idxworker.debug }}"
            - name: DATAONE_AUTH_TOKEN
              valueFrom:
                secretKeyRef:
                  name: dataone-token
                  key: DataONEauthToken
                  optional: true

Should also be able to close Issue #41 at that point

Should also be able to close Metacat Issue #1700 at that point
