Adds separate config for pydap gateway

The registration process will use the entry under server for pointing external clients to the the URL
where the datasets can be accessed via DAP.  The lightweight dap server (gateway) will use the container
configuration: container.pydap_gateway.web_server for the host and port to launch on.

This should make load balancing easier to configure.

Example:
The registration process will have the following config:

server:
  pydap:
    host: pydap.oceanobservatories.org
    port: 5000

One pydap gateway will have:
container:
  pydap_gateway:
    web_server:
      host: pydap-slave1.oceanobservatories.org
      port: 9001

Another will be
container:
  pydap_gateway:
    web_server:
      host: pydap-slave2.oceanobservatories.org
      port: 9002
