On select Datasources, vendors have a channel for the consumption
of all supported user data types via a special channel called
vendor data. Any scripts in the ``scripts/vendor`` directory in the datasource
will be run when a new instance is first booted. Scripts will be run in
alphabetical order. This module allows control over the execution of
vendor data.
