This commit moves the OpenFaaS gateway from using in-process
basic-auth for everything to use an external auth URL instead.

When auth is not enable, this functionality is not added to the
handlers and behaves as before. When enabled, the configured
plugin with authenticate requests.

Tested on Docker Swarm with positive and negative tests.

Fixes issue by adding unit test to make sure the body from
the plugin is written correctly and proxied to the client.

Fix for external auth wrapper handler. Written by introducing
a broken unit test. Whenever the auth plugin returns a request
as not authorized, we must pass back any headers set by the
plugin.

Fixes issue found in e2e testing where the headers were not
being passed to the basic-auth-plugin. This change makes sure
the upstream check gets all headers copied in before making
the call.

Tested with negative unit tests before writing fix.

These two functions are effectively the same, with the former
being a wrapper for the later.

An explicit timeout is passed to the handler and a new unit test
proves that the functionality is in place. A additional return
statement was needed in the handler as pointed out by
@stefanprodan.

This commit adds an external auth handler which can be used to
wrap existing handlers, so that they delegate their requests
to an upstream URL before allowing a request to pass through
to an upstream API.

New handler tested with unit tests.

Headers such as Realm / etc are important for auth proxies, so
this change and unit test make sure they get copied back to the
client.

As per comment from @stefanprodan, the path for the handler
was incorrect in the run stage of the Dockerfile.
