Failed to retrieve data node status via `get_data_node()`

[hongyuanjia]

The LLNL ESGF Node has transferred to use the new Metagrid UI, which makes get_data_node() fail to parse the data node status. Workrounds include:

• Use the legacy interface from other federated ESGF Nodes
• Update the parse to handle Metagrid UI

Thanks for the workaround! Was having this issue earlier today.
