net/http adapter for fastglue

Fastglue-Adapter

Helper functions for converting net/http request handlers to fastglue request handlers.

Overview

A port from fasthttpadaptor. While this function may be used for easy switching from net/http to fastglue, it has the following drawbacks comparing to using manually written fastglue request handler:

• A lot of useful functionality provided by fastglue is missing from net/http handler such as webhooks.
• net/http -> fastglue handler conversion has some overhead,so the returned handler will be always slower than manually written fastglue handler.

So it is advisable using this function only for quick net/http -> fastglue switching or unavoidable situations.
