kapacitord ignores commands following the `-config` flag

kapacitord ignores command line verbs like help, version, and downgrade if a configuration file is passed with the -config flag. This means that the downgrade flag cannot be used for any kapacitor.db file that is not in the default location.

This appears to be the case when the flags is before the command on the command line. It may not be the case when the command is first, e.g. kapacitord downgrade -config <path>. Testing is underway.
