use 1.14 for choosing updated deps. Using current tip (1.17) will cause tests fail as some packages are not supporting 1.14.

* split tests into separate blocks
added an error pair to IdentifierExtractor
Includes deny handler for explicitly denying requests
* adds comments for exported members Extractor and ErrorHandler

This reintroduces support for Go modules, as v4.
CloseNotifier() is removed as it has been obsoleted, see https://golang.org/doc/go1.11#net/http
It was already NOT working (not sending signals) as of 1.11 the functionality was gone, we merely
deleted the functions that exposed it. If anyone still relies on it they should migrate to using
`c.Request().Context().Done()` instead.
Closes#1268, #1255
