templates/common/util_functions:

* increased minimum memory threshold for ram disk
* moved apt_add_repo and friends to common/install_functions

templates/dask/util_functions:
* validating conda tarball before caching to gcs

templates/generate-action.pl:
* improved usage documentation a little

templates/gpu/install_functions
* using /opt/conda/miniconda3/bin/python3 instead of /usr/bin/ for
  venv pre-install
