Routeless proxy allowed no HTTP path to be given when a Header
X-Function: name was given. This has been deprecated - I am
unaware of any usage of the feature.

Get is a supported method so this test failed, I've now changed
this to an unsupported method - i.e. HEAD to trigger the error
and keep the test.

Proxy body was being passed correctly due to placement of defer
statement. This has been moved into outer scope to resolve issue.

HTTP proxy was not passing query-string upstream. This change
reinstates the behaviour through TDD - adding test coverage and
automated regression testing.

Forwarded requests were being logged in the function metrics and
I saw this when doing some testing on auto-scaling with K8s.
This change removes the call to the Prometheus notifier for any
calls which are forwarded to the provider and retains them for the
functions.

If the watchdog is sent SIGTERM from an external process then it
should stop accepting new connections and attempt to finish the
work in progress. This change makes use of the new ability in Go
1.9 and onwards to cancel a HTTP server gracefully.
The write_timeout duration is used as a grace period to allow all
in-flight requests to complete. The pattern is taken directly from
the offical example in the Golang documentation. [1]
Further tuning and testing may be needed for Windows containers which
have a different set of signals for closing work. This change aims
to cover the majority use-case for Linux containers.
The HTTP health-check is also invalidated by creating an and
expression with the existing lock file.
Tested with Kubernetes by deploying a custom watchdog and the
fprocess of `env`. Log message was observed when scaling down and
connections stopped being accepted on terminating replica.
Also corrects some typos from previous PR.

0.7.7 allows direct function access bypassing the provider - this makes
the throughput increase and skips a HTTP hop that is no longer required.

This commit replaces occurences of http method strings with the
corresponding consts from the http package.
*Note* UPDATE is not strictly speaking a valid method and as such isn't
part of the http package (should be a PUT or PATCH?)

Adds a pair of configuration options for performance tuning. The
gateway can now invoke functions directly and can bypass the
provider. See updated table in README.md for configuration values.
BaseURLResolver is added with unit tests that decouples resolving
upstream URL from the reverse proxy client code.
- SingleHostBaseURLResolver resolves a single upstream host
- FunctionAsHostBaseURLResolver resolves host based upon conventions
within the URL of the request to a function for direct access

Integration test for combine_output should use stat instead of
man as man is not installed in the CI system.

This enables an often-requested feature to separate stderr
from stdout within function responses. New flag combine_output is on
by default to match existing behaviour. When combine_output is set
to false it redirects stderr to the container logs rather than
combining it into the function response.
Tested with unit tests for default behaviour and new behaviour.
