[FIX] prioritize cli options over yaml #5495

Proposed change(s)

steps to reproduce the bug:

run exp1 for 1M steps
initialize exp2 from last one with yaml["checkpoint_settings"]["initialize_from"] and continue running for eg. 200k
resume exp2 from cmd and the step count continues from 1M instead of 200k

solution: checkpointSetting class now prioritize the command line arguments (resume or initialize_from for now) over conflicting yaml options. yaml option is nuke with a warning

+ # ignore init if resume set
+ full_args.append("--resume")
+ opt = parse_command_line(full_args)
+ assert opt.checkpoint_settings.initialize_from is None # ignore init if resume set
 assert opt.checkpoint_settings.resume is True



Do we need a test to check if they were both set in the YAML but not the CLI? I think we can do this in the test_settings.py.

Forgot in my last approval - add this bug fix to the CHANGELOG.md file and reference the PR before merging.
