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.

Allows alerts to trigger functions to scale when they
also have an optional namespace set.
Tested e2e with Kubernetes 1.15 and a non-default namespace.

- 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.

Tested on Docker Swarm for scaling up, already scaled and not
found error.
