CORE-6039 added resolve-data-type proxy to data-info

The function resolve-data-type was added to donkey.clients.data-info that acts as a pass through to data.services.filesystem.icat's function of the same name.
CORE-6039 switched metadata namespaces off icat namespace

The donkey.services.metadata namespaces now use donkey.clients.data-info instead of donkey.services.filesystem.icat directly.
