Review Comment:
   While I was debugging CI failures, I noticed that the state_sampler is None 
when operations are run in a non-streaming context. The autocomplete_test was 
an example of this. 
   
   Adding the Noop state ensures that the code is safe to execute in all 
contexts, both for the new timer metric and or the existing start, process, and 
finish states.
