The terra-jupyter-gatk image is not compatible with GATK #464
Description
The Python environment in the latest terra-jupyter-gatk image is not compatible with most of the Python-based GATK tools, which is causing problems for downstream GATK users and Terra/GATK workshop attendees.
Would it be possible to make older images available as an option?
The official GATK conda environment, reflecting current tool requirements, is here: https://github.com/broadinstitute/gatk/blob/master/scripts/gatkcondaenv.yml.template
