This feature was first introduced in Tungsten Dashboard version 1.0.9-61
There are two confirmation prompts before the definitions are removed.
Once removed, this action cannot be undone. You will have to re-create the definitions.
Only definitions that are stored as single JSON files in the
{WEBROOT}/conf.d/
subdirectory will be
deleted. Clusters defined in the config.php
file will not be removed.
