chore(typescript): extract handlers types

[leonardobazico]

I've been rewriting the handlers' types on my current project. To avoid it this PR extract handlers type and expose them

Also made the callbacks have the same types implemented on the http-proxy

Coverage remained the same at 84.953% when pulling 6e0e157 on leonardobazico:types into 3115dae on chimurai:master.

Now I got the error:

Property 'query' does not exist on type 'IncomingMessage'.

pseudo code:

import { createProxyMiddleware } from 'http-proxy-middleware';

export default createProxyMiddleware({
  // ...
  onProxyReq: (proxyReq, req, res) => {
    // ...
    if (req.query && req.query?.locale) { // <--- ERROR: Property 'query' does not exist on type 'IncomingMessage'.ts(2339)

Shouldn't this remain Request (express.Request)?
