WS-2799 HTC 23 upgrade

This upgrades our workflow service container and local HTC containers to use HTC 23 (the version after HTC 10).

A start for the upgrade and testing documentation (open to suggestions of where it should live): https://open-confluence.nrao.edu/display/SDT/HTCondor+Upgrade

I hit a snag in testing that showed environment variables now need to be explicitly passed through the DAG file in workflows that use a DAG (see references below). After inspecting our templates, pexes, and service code, I only found CAPO_PROFILE to be an expected environment variable that needs passed through the DAG. std_calibration_and_imaging works with the DAG fix in place and I'll be testing the others.

Refereneces on DAG issue: (1) How getenv = True allows all environment variables through. (2) Why others think this is a bad idea and how condor_dagman doesn't allow it anymore. (3) How to pass envvars in the DAG.
