Skip preprocessor step in Actors

Skip preprocessor step in Actors

Modified Actors to skip the preprocessor step if the "preprocessed" flag
is set to true in the parameters.  Did not add any error checking code
to ensure the data was actually available to the operation - will add
that once the properties are being set by the application code.
Extracted common code in GrpcOperationTest into the setup method.
