pass optype to setResourceReadMany from SetResource (#630)

Description of changes:

Currently, if the resource output shape is a list, code-gen triggers the 
readmany output generator. 
When doing so, it does not pass the operationType, which causes it to 
lose some of its functionality, which in this case was the ability to 
ignore setting resources for a desired method.
With these changes, even sdk outputs that have a list as output type 
will be able to configure Create/Update/Delete set config in 
generator.yaml
