On a cluster reproducing #30832, /_status/range/1 results in the following output:

{
  "error": "all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: failed to write client preface: io: read/write on closed pipe\"",
  "code": 14
}

All nodes are live, and even if they weren't, "read/write on closed pipe" looks unlike any error expected in that setting.

We should do a better job at making sure the debug commands work when clusters are unavailable.
