Returns the cluster's current health in JSON format, with the following variables:
-- `status`: one of `Healthy`, `Degraded` or `Unavailable`:
- - Healthy: Garage node is connected to all storage nodes
- - Degraded: Garage node is not connected to all storage nodes, but a quorum of write nodes is available for all partitions
- - Unavailable: a quorum of write nodes is not available for some partitions
-- `known_nodes`: the number of nodes this Garage node has had a TCP connection to since the daemon started
-- `connected_nodes`: the nubmer of nodes this Garage node currently has an open connection to
-- `storage_nodes`: the number of storage nodes currently registered in the cluster layout
-- `storage_nodes_ok`: the number of storage nodes to which a connection is currently open
