Revise HttpConnection so it can be used with either client or server

Move `response` member variable into `HttpConnection` as both client and server have this.
Move `getResponse()` method from `HttpClientConnection` into `HttpConnection`
Add virtual `getRequest()` method to HttpConnection
Move applicable methods from `HttpClientConnection` into `HttpConnection`

Note: `send(HttpRquest*)` made virtual in previous commit
