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.

The queue's name will be consumed by the queue worker to
publish to other topics / slow queues.

* 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.

There was a case where a deployment with a single namespace on
faas-netes would show the namespace suffix for all functions.  we didn't
need to show this because the gateway will proxy to the default
namespace for fns without the namespace siffix.

This was tested on Swarm (no suffix), faas-netes (single namespace, no
suffix) and faas-netes, multi-ns, suffix shown.
