Setup.py requirements break xcube docker build

[mattfung]

Description

When building xcube in docker using default xcube 0.6.1 Dockerfile, installation of xcube-cds plugin fails due to the xcube requirements entry in the setup.py file.

Perhaps the setup.py requirements should be commented out like the xcube-sh plugin
