Updating name of activation-scale

[psschwei]

Signed-off-by: Paul S. Schweigert [email protected]

Release Note

Adds a `autoscaling.knative.dev/activation-scale` annotation that allows the user to set a minimum number of replicas when not scaled to zero. Note that the initial target scale for a revision is still handled by `initial-scale`; `activation-scale` will only apply on subsequent scales from zero.
