Ability to set various CLI options in the execution-environment.yml file

[ansiblejunky]

Currently the container runtime option can only be passed to ansible-builder via CLI argument. It would be nice to add this option in the config file execution-environment.yml. If the user wishes to override the value in the config file, they can still choose to provide the CLI argument --container-runtime which would take precedence.

I would like to address this generally. Not just for --container-runtime, but other options like --output-filename as well.

@AlanCoding Fully agree. I changed the title to be more generic.
