GlusterFS plugin throws version deprecation error

[Przemyslaw Kaminski]

This error is shown when instaling GlusterFS plugin on 6.1:

DEPRECATION WARNING: The plugin has old 1.0 package format, this format does not support many features, such as plugins updates, find plugin in new format or migrate and rebuild this one.

Since it's a certified plugin it should have an up-to-date info in metadata.
