feature: Support role as PipelineParameter in Processor class

[francescoalongi]

Issue #, if available:
No issue associated

Description of changes:
Currently, the SDK throws an error if the role parameter of the Processor class is passed as PipelineParameter because it expects only strings. With this modification the class Processor is now able to accept the role parameter as PipelineParameter, enabling then the possibility of feeding the role parameter when the pipeline is triggered.

Testing done:
