Health check endpoints

MSR exposes several endpoints that you can use to assess whether or not an MSR replica is healthy:

• /_ping: Checks if the MSR replica is healthy, and returns a simple JSON response. This is useful for load balancing and other automated health check tasks.

• /nginx_status: Returns the number of connections handled by the NGINX MSR front end.

• /api/v0/meta/cluster_status: Returns detailed information about all MSR replicas.
