gateway

Users need a shutdown hook to close a server. The pattern is fairly often used in the Armeria examples.

We can add a shortcut method for automatically closing a server or a client.

server.closeOnShutDown()
server.closeOnShutDo

It looks like the Mercurius Gateway service expects "errors" to exist in the response, however, if I have a fastify plugin that throws an error before it ever hits GraphQL, then the gateway emits an error.

{
  "errors": [
    {
      "message": "Cannot read property 'profile' of undefined",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
