Use expand_wildcards to limit bad API responses

[VimCommando]

Certain API calls will fail if there are closed indices in the cluster, such as _nodes/stats. When there is a closed index it will respond with:

Bad Request. Rejected
{
  "error" : {
    "root_cause" : [
      {
        "type" : "index_closed_exception",
        "reason" : "closed",
        "index_uuid" : "LEF6dp1xTC2dkNCEMRtUUQ",
        "index" : "syslog"
      }
    ],
    "type" : "index_closed_exception",
    "reason" : "closed",
    "index_uuid" : "LEF6dp1xTC2dkNCEMRtUUQ",
    "index" : "syslog"
  },
  "status" : 400
}

The multi-target syntax allows adding ?expand_wildcards=open as far back as 6.8:

With additional ?expand_wildcards=open,hidden options in 7.x:

If we add this to the API calls we can hopefully prevent parsing failures when trying to run the diagnostic through the analyzer.
