dbbuilder has unresolvable conda dependencies

[cat-bro]

mamba install -y -n mulled-v1-20ff818e83327f1e474d5c0ed97892f5b23f3b1283b853ee7957449e035b4eed --quiet --override-channels -c conda-forge -c bioconda -c defaults wget=1.20.1 python=3.8 requests=2.20.1
Encountered problems while solving:
  - package requests-2.20.1-py27_1000 requires python >=2.7,<2.8.0a0, but none of the providers can be installed

The combination of conda dependencies could not be resolved and Galaxy was attempting to build the environment at runtime for each job, which led to a lot of overhead for job handlers. I've switched to using requests=2.22 with the env name that galaxy expects and this seems to work OK.
