Publish license details

Amazing work on the exporter!

The only missing set of metrics we needed was license information so that we could alert on expiration time approaching.

Hi @c4milo,

this certainly makes sense. As we are not using licensed features of ES, can you give me a hint where (API endpoint) I can find them?

Hey @zwopir, sure! Here it goes:

$ curl http://localhost:9200/_xpack/license
{
  "license" : {
    "status" : "active",
    "uid" : "<redacted>",
    "type" : "basic",
    "issue_date" : "2018-08-14T00:00:00.000Z",
    "issue_date_in_millis" : 1534204800000,
    "expiry_date" : "2019-08-14T23:59:59.999Z",
    "expiry_date_in_millis" : 1565827199999,
    "max_nodes" : 100,
    "issued_to" : "<redacted>",
    "issuer" : "Web Form",
    "start_date_in_millis" : 1534204800000
  }
}

Hi @c4milo,

sorry for catching up so late. Is the feature still needed?

Although some time has passed and the original author hasn't answered, I'd like to say that I'm currently looking forward to this feature. We'd also like to alert when the license is expiring.
