We can use the internal buffering of the json_stream instead of
manually building JSON-RPC calls. This makes it a lot easier to handle
these requests.
Notice that we do not flush concurrently and still buffer all the
things, but it avoids double-buffering things.

If the plugin fails to respond to we may end up hanging indefinitely,
so we limit the time we're willing to wait to 10 seconds.

I had this really contorted way of iterating over options that could
cause valgrind to choke. This is the much more intuitive way to
iterate.

The final step in the JSON-RPC passthrough: map the result we got from
the plugin back to the original request we got from the client.

This is the final step to get the plugins working. After parsing the
early options (including `--plugin`), then starting and asking the
plugins for options, and finally reading in the options we just
registered, we just need to assemble the options and send them over.

We also make `--help` a non-early arg so it allows for the plugins to
register their options before printing the help message. The options
themselves are stored in a separate struct inbetween them being
registered and them being forwarded to the plugin. Currently only
supports string options.

Also includes some sanity checks for the results returned by the
plugin, such as ensuring that the ID is as expected and that we have
either an error or a real result.
