This change removes the direct functions option which was
used originally for Docker Swarm. The Community Edition will
rely on the faas provider - faas-netes / faasd for load-balancing
of requests.
Direct Functions is required in order to delegate load-balancing
to Istio, Linkerd or some other kind of service mesh.
Tested by deploying a modified gateway image to a KinD cluster,
deploying the env function, and scaling to two replicas. This
balanced the load between the two pods by printing out the names
and then I ran a test with hey which returned 200s for all the
requests.
The prober which was part of the Istio support is no longer
required in the CE gateway so is removed for simplicity.

Introduces a single-flight call to a function's health
endpoint to verify that it is registered with an Istio
sidecar (Envoy) before letting the invocation through.
Results are cached for 5 seconds, before a probe is
required again.
Tested without Istio, with probe_functions environment
variable set to true, I saw a probe execute in the logs.
Fixes: #1721 for Istio users.

* Add service target metric
* Add service min replicas metric
* Add scale type metric
These combined allow new auto-scaling modes and parameters
for OpenFaaS Pro customers.

This appears to have broken CI at least three times now and
prevented us from shipping a release binary for a tag.

Enables publishing to various topics according to annotations
on the functions. The function cache is moved up one level so
that it can be shared between the scale from zero code and the
queue proxy.
Unit tests added for new internal methods.
Tested e2e with arkade and the newest queue-worker and RC
gateway image with two queues and an annotation on one of the
functions of com.openfaas.queue. It worked as expected including
with multiple namespace support.

* This experimental patch records metrics as invocations start
so that the metrics can be used to make better scale to zero
decisions in faas-idler.
Tested with Kubernetes on a single-node cluster, metrics
reported as expected. Existing metrics still report.

This change which has been tested on armhf and x86_64 removes

This corrects an issue where the error body was being hidden
for the external auth handler. It also adds the ca-certs into
the runtime Docker image for when the gateway is calling an
external plugin exposed over HTTPS.
Tested with OAuth2 plugin.

- extracting this package means it can be used in other components
such as the asynchronous nats-queue-worker which may need to
invoke functions which are scaled down to zero replicas.

Existing code has been used for scaling up and querying replicas.
This meant the new code was deleted and there is less duplication
now.
The cache store a whole query response rather than just the
available replica count and the tests were updated. This has been
tested with Docker swarm and the image:
openfaas/gateway:scale-17-07-2018
This feature now needs the env-var of scale_from_zero to be enabled
in order to turn on the scaling behaviour.

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.
