APT source whitelist request for Elasticsearch 6

[benpbolton]

I would like to request that Elasticsearch 6 repo be added to the apt source whitelist:

deb https://artifacts.elastic.co/packages/6.x/apt stable main

The APT signing key is at https://artifacts.elastic.co/GPG-KEY-elasticsearch

Detailed setup instructions are here if necessary.

eg.

  {
    "alias": "elasticsearch-6.x",
    "sourceline": "deb https://artifacts.elastic.co/packages/6.x/apt stable main",
    "key_url": "https://packages.elastic.co/GPG-KEY-elasticsearch"
  },

Thanks!
