Test connection to one or more Cluster nodes

[alexjpwalker]

Problem to Solve

Currently, there's no easy way to check the health of Cluster server nodes.

Current Workaround

SSH into each machine individually, run jps, assuming that if the node is alive then it is responsive. Check its logs to make sure. Alternatively, try creating a Cluster client to each node and listing databases.

Proposed Solution

Add an API for testing connection to a single instance of Core, a single Cluster node, or all registered Cluster nodes

Additional Information

This should then be implemented in Studio.
