Add the translate section of the translate_config to the usual config.yml file.

Instead of requiring a separate translate_config.yml file the translate: section could be part of the config.yml file.
The --translate option could be removed from the experiment.py code and experiments would translate iff the translate section is present.

This would reduce file management and make it easier and quicker to configure projects that use this feature.

+1 This would also make it much easier to automate within the onboarding dashboard and clowder proper.
