[7.x] Resolve index API

[danhermann]

Provides a /_resolve/index/{name(s)} endpoint that resolves the specified name(s) and/or wildcard expressions to indices, aliases, and data streams.

Multiple expressions and remote clusters are supported. E.g.:

GET /_resolve/index/f*,remoteCluster1:bar*

The response is in the format:

{
  "indices" : [
    {
      "name" : "foo-000001",
      "attributes" : [
        "open",
        "hidden"
      ],
      "data_stream" : "foo"
    },
    {
      "name" : "foo_closed",
      "attributes" : [
        "closed"
      ]
    },
    {
      "name" : "remoteCluster1:bar-01",
      "attributes" : [
        "open"
      ]
    },
    {
      "name" : "freeze-index",
      "aliases" : [
        "f-alias"
      ],
      "attributes" : [
        "open",
        "frozen"
      ]
    }
  ],
  "aliases" : [
    {
      "name" : "f-alias",
      "indices" : [
        "freeze-index",
        "my-index"
      ]
    }
  ],
  "data_streams" : [
    {
      "name" : "foo",
      "backing_indices" : [
        "foo-000001"
      ],
      "timestamp_field" : "@timestamp"
    }
  ]
}

The attributes array for an index will always contain either open or closed as well as hidden or frozen if either of the latter two states applies to the index.

The API supports the standard expand_wildcards parameter as used on other index APIs.
