Publish config to allow two locations for each API

[adamkdean]

It would be great if Publish config would allow two locations for each API.

Currently we have:

  {
    "name": "my_cat_blog",
    "host": "http://my.cat.blog",
    "port": 80,
    ...
  }
]

But when running in Docker, we may want external traffic to go via a proxy and internal traffic to not do so, i.e. frontend -> https://my.cat.blog, backend: http://my_cat_blog_api etc.

"apis": [
  {
    "name": "my.cat.blog",
    "external": {
      "host": "https://api.my.cat.blog",
      "port": 443
    },
    "internal": {
      "host": "http://my_cat_blog_api",
      "port": 80
    }
    ...
  }
]
