Make a button on the admin interface to read and save the current application.yml file for PyFerret config.

Currently the only way to change the PyFerret config is through restart of the container. It would be handy to reinit via the admin console so the rest of the container processes can go on uninterrupted while LAS is reinitializing the PyFerret config.

It's a one liner (after auto-wiring the service) in the admin controller...

initializationService.initEnvironment()
