Alex Ellis (VMware) e67d45caa1 Add feature: scale from zero to 1 replicas ...

This change allows functions to be "idled" or scaled to zero
replicas and then be invoked later on. There is a penalty to
scaling up - the API gateway proxy will block until the function
is ready.

A cache is included to off-set the calls to upstream API to check
on readiness along with unit tests.

Testing via scaling to zero replicas and then invoking function.
On Swarm I observed 3 seconds on an Intel Nuc i5 for scaling back
from zero replicas.
