CM/CMX v3.2.0: many new features

I have added many important features to CMX pending for a very long time:

• added utils.test_input to test if input has keys and report them as error
• added prefix_cmx key to cmr.yaml to customize cmx pull repo
• improved CMX logging (-log and -logfile): #1317
• print control flags in help (cmx -h | cmx -help): #1318
• fail if control flag is not recognized: #1315
• added -repro flag to record various info to cmx-repro directory: #1319
• print call stack when error > 32 to be able to trace error cause: #1320
  can be combined with -log=debug and -logfile

CM v3.0.1: prototyping simpler interface

CM v3 includes a prototype of a simpler and cleaner version of Python cmind.access() and CLI. It should not influence existing CM4MLOps automation scripts and workflows for MLPerf and other projects from CM v2.x . Both interfaces will co-exist in the future.

CM v2.4.0: extension to CM repos to install requirements.txt

• added install_python_requirements to the CM repo description (cmr.yaml) to install requirements to a current python with CM installation if needed

CM V2.3.9: improved "cm init" and CLI

• added --min == --skip to cm init for readability
• added --checkout to cm init to handle checkout
• added support to set CLI parameter to False if it ends with -,
  i.e. --no-cache- -> i['no_cache'] = False
--no-cache -> i['no_cache'] = True

CM V2.3.8: better handling of CM git repos

• added --skip and --url flags to cm init
• added support to pull CM repos using --url with "git@"

CM V2.3.7: better support for debugging

• added cmind.core.debug to make it easier to debug CM automations
• added env CM_CORE_SKIP_FIX_REPO_PATH to skip fixing non-existent repo paths

CM v2.3.6: minor fixes

• fixed "cm init" on Windows
• added basic CM tests on MacOS
• added "cm add script" tests
