2.3.0-xcube-dev.4

Changes 2.3.0 (in development)

• Optimisations in the DATA SOURCES panel (that have been enabled by
  using xcube in the backend):

  • Initalising the "CCI Open Data Portal" data store
    is now accellerated by a magnitude.
  • Local caching of remote data sources when opening datasets
    is now much faster and more reliable.
  • Added new experimental store "CCI Zarr Store" that offers
    selected CCI datasets that have been converted to Zarr format
    and are read from JASMIN object storage.
  • Ability to add more data stores has been greatly improved.

• We now obtain Cate Hub's status information from a dedicated GitHub
  repository cate-status.

• Adapted to changed cate-hub API. (An API response no longer has
  status and result properties, instead a response is the result
  and the response status is represented by the HTTP response code.)
