add additional surprise checking for actions scenes/filters/

[mclarsen]

We currently check for surprises in filter parameters, but not in higher level stuff.

Here is an example:

- 
  pipelines: 
    pipe1: 
      f0: 
        params: 
          bins: "32"
          field: energy
          sample_rate: "0.05"
        type: histsampling

Generates:
