Arvados

For various Python client tools, our documentation goes on a tangent to tell you how to install the dependencies to build pycurl. Since we wrote that, a lot has changed:

• Pre-built wheels are better supported both by distros and packages
• We now always tell users to install in a virtualenv (after #20543)

On a few distributions on the old end of what we support, try the most naive way to install our Python packages:

python3 -m venv arvenv
arvenv/bin/pip install arvados_fuse arvados-cwl-runner crunchstat_summary

If that works, then wheels have obsoleted the build instructions, and they can be removed from the documentation to simplify it.
