@mattclay any suggestions on handling ansible-test better?

[mattclay]

Changes to terminal support should be merged to ansible-core first. After that, a separate PR can be used to update ansible-test if required.

[webknjaz]

@mattclay yeah, I can split the commits. It was just convenient to test it together. I confirmed that both ansible-test changes are needed for this to work there. I was just hoping that you'd be able to find another place to update in case it's somehow possible to patch just one file instead of two..

@bcoca remind me plz — did you want me to prefix the defaults for COLOR_* in lib/ansible/config/base.yml with smart and process that in ansible.utils.color.parsecolor()? Would this mean that ansible.constants.COLOR_CODES would just get an extra of keys prefixed with smart?
