Return the name of the package that owns the file. Multiple file paths can
    be passed. Like :mod:`pkg.version <salt.modules.opkg.version`, if a single
    path is passed, a string will be returned, and if multiple paths are passed,
    a dictionary of file/package name pairs will be returned.

    If the file is not owned by a package, or is not present on the minion,
    then an empty string will be returned for that path.

    CLI Example:

        salt '*' pkg.owner /usr/bin/apachectl
        salt '*' pkg.owner /usr/bin/apachectl /usr/bin/basename

def owner(*paths, **kwargs):  # pylint: disable=unused-argument
