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.
Ref: https://github.com/openfaas/nats-queue-worker/issues/32
Tested on Docker Swarm for scaling up, already scaled and not
found error.

- as reported on Slack and in issue #931 the gateway scaling code
was scaling to zero replicas as a result of the "proportional
scaling" added by @Templum's PR. This commit added a failing test
which was fixed by adding boundary checking - now if the scaling
amount is "0" we keep the current amount of replicas.

Previous PR from Simon or Ken broke build due to missing gofmt
in the PR. This PR applies it to resolve the build issue.

Introduced an new label to set the scaling factor that is used to calculate th proportions, setting it to 0 also allows to disable scaling.
Updated the tests to reflect the changes and added a new test which shows that setting the scaling factor to 0 indeed does disable scaling.
Ensured that the scaling factor is always between [0 and 100].
