List the files that belong to a package, grouped by package. Not
    specifying any packages will return a list of _every_ file on the system's
    package database (not generally recommended).

    CLI Examples:

    .. code-block:: bash

        salt '*' pkg.file_list httpd
        salt '*' pkg.file_list httpd postfix
        salt '*' pkg.file_list
