Closes #584 (closed) These methods are removed included their unit tests:

--
parcel.routes.js-   * /tracking/{sessionId}/investigation/id/{investigationId}/shipment/id/{shipmentId}/parcel:
parcel.routes.js-   *   get:
parcel.routes.js:   *     deprecated : true
--
parcel.routes.js-   * /tracking/{sessionId}/investigation/id/{investigationId}/parcel/id/{parcelId}:
parcel.routes.js-   *   get:
parcel.routes.js:   *     deprecated : true
--
parcel.routes.js-   * /tracking/{sessionId}/parcel/status/{status}:
parcel.routes.js-   *   get:
parcel.routes.js:   *     deprecated : true
--
parcel.routes.js-   * /tracking/{sessionId}/investigation/id/{investigationId}/shipment/id/{shipmentId}/parcel:
parcel.routes.js-   *   post:
parcel.routes.js:   *     deprecated: true
--
parcel.routes.js-   * /tracking/{sessionId}/investigation/id/{investigationId}/shipment/id/{shipmentId}/parcel:
parcel.routes.js-   *   put:
parcel.routes.js:   *     deprecated : true
--
parcel.routes.js-   * /tracking/{sessionId}/investigation/id/{investigationId}/shipment/id/{shipmentId}/investigation/id/{toInvestigationId}/parcel:
parcel.routes.js-   *   put:
parcel.routes.js:   *     deprecated : true
