The instance schema already includes host_ip and port fields we don't do anything with (but are accurate).
We should use them to generate the hostsByName sections currently in the PHP files as well. This will likely also involve creating a bunch of instance objects that aren't pooled anywhere / aren't in the usual sectionLoads location; we'll need to include them in the output hostsByName config regardless.
