server: add support for range trigger overload actions #12352

  1. Add 'scaling' to OverloadManager action states 

    Extend the existing overload action states with a 'scaling' state with a
value in the range [0, 1]. The scaling state is not used yet, but will
be used to support actions that can take partial effect even if resource
pressure is below saturation.

  2. Add Range trigger to Overload Manager 

    Add a Range trigger that will produce overload action states that are in
between the inactive and saturated states. This will enable the creation
of actions that take more effect as load increases.
