Sets a new default maximum scale limit of 5 replicas out of
the box for CE users, CE meaning "Community" rather than
"Commercial".
The increment factor of 10 vs 25 should not make a difference
to genuine community and hobbyist users.
Tested and verified with unit tests and hey with a CE cluster
where the maximum limit was reached over several minutes,
finally going back to 1 replica.

* Add service target metric
* Add service min replicas metric
* Add scale type metric
These combined allow new auto-scaling modes and parameters
for OpenFaaS Pro customers.

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.
