Disabling access log for status endpoint

Customizable DNS resolver settings

If a request or response have multiple Content-Type headers, this make
sure the latest one is returned, so mimeType is guaranteed to be a
string, and not an array.

Fix for Kong#584

[fix/alf_serializer] always ensure mimeType is a string

Replacing the previous uuid library with our lua_uuid

- resolver is not a plugin anymore
- resolver has `before` and `after` methods for each context
- the resolver is responsible for carrying context variables from one
  context to another (using `ngx.ctx`)
- it might be renamed in the future. It does not just do resolving
  anymore.
- fix: now includes latency headers in responses (was missing before)

When a plugin sends a response, it is always through `ngx.exit` which
already exits all phase handlers.

- it handles reports, ctx variables being carried along the request,
resolver execution (to find the correct API to route).
- rename nginx $backend_url to $upstream_url
- rename nginx $backend_host to $upstream_host
- use `ngx.ctx.upstream_url` to store the currenct upstream URL. All
  plguins can stil laccess and modify this value before it is given to
  `ngx.var.upstream_url` for proxy_pass.
