ansible-navigator run does not allow using yaml output

[myllynen]

Many execution environment images, such as the ones provided and supported by Red Hat, unconditionally set ANSIBLE_STDOUT_CALLBACK=awx_display which prints out errors in json not in yaml and there seems to be no way for a user to override this. Error messages in yaml are often much easier than in json.

While it seems that using awx_display may be required with ansible-runner it would help developers working on the command line with ansible-navigator to be able to use the yaml output format as they often do with ansible-playbook.

Thanks.
