Configure ewoks arguments

https://gitlab.esrf.fr/icat/icat-plus/-/blob/master/app/controllers/ewoks.controller.js?ref_type=heads#L139

The worker options have been updated on the icat+ test server (dau-dm-03) with

worker_options: {
      queue: "id23eh1_2",
      queue: "id30a2",
    },

We should move this to a configuration file.
