Conrad Ludgate 32126d705b proxy refactor serverless (#4685) ...

## Problem

Our serverless backend was a bit jumbled. As a comment indicated, we
were handling SQL-over-HTTP in our `websocket.rs` file.

I've extracted out the `sql_over_http` and `websocket` files from the
`http` module and put them into a new module called `serverless`.

## Summary of changes

```sh
mkdir proxy/src/serverless
mv proxy/src/http/{conn_pool,sql_over_http,websocket}.rs proxy/src/serverless/
mv proxy/src/http/server.rs proxy/src/http/health_server.rs
mv proxy/src/metrics proxy/src/usage_metrics.rs
```

I have also extracted the hyper server and handler from websocket.rs
into `serverless.rs`
