The UPDATE HTTP Method isn't valid and not currently in use by the
watchdog so removing it.

Signed-off-by: John McCabe <john@johnmccabe.net>

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

Tested with Kubernetes (faas-netes) and faas-swarm through UI, CLI
calling system endpoints and functions directly.

readconfig.go was altered due to bug reading default value. This was
tested by adding unit tests to readconfig_test.go for positive and
negative scenarios.

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

Signed-off-by: Alex Ellis (VMware) <alexellis2@gmail.com>

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.

HTTP port can now be overriden through use of "port" environmental
variable.

Prefer messaging "want" over "wanted" in error messages, this is more
idiomatic Golang.
