Missing metric "Drives Free Inodes" from widget in minio console, as the console widget is using incorrect metric "minio_cluster_drive_free_inodes" which is not exposed in minio.

Expected Behavior

"Drives Free Inodes" widget from the Resource tag should have metric shown up.
Missing metric "Drives Free Inodes" widget should use the metrics "minio_node_drive_free_inodes"

Possible Solution

Change the metric reference of "minio_cluster_drive_free_inodes" to "minio_node_drive_free_inodes" in
