- this reinstates the cache to reduce the count of lookups to the
provider when checking if scaling is needed.

117707df14 Enable backoff/retries on scaling up
- this change is needed for Docker Swarm which may give an error
when several concurrent requests come in to scale a deployment.

Tested on Docker Swarm before/after with the hey tool and figlet
scaled down to zero replicas.

9cea08c728 Extract scaling from zero
- 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.

Ref: https://github.com/openfaas/nats-queue-worker/issues/32

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