docs(samples): Updated Samples for v2.0.0 Client Library (#365)

* docs(samples): Updated Samples for v2.0.0 Client Library

- Added Examples for FetchProcessorTypes, CreateProcessor, ListProcessors, DeleteProcessor, DisableProcessor, EnableProcessor
- Added example parameters for processorVersion and FieldMask
- Removed references to 'v1' in imports (default is v1)
- Changed File types Documentation link in comments
- Corrected Human Review test method name

* docs(samples): Added Sample Code for Operations Functions

* 🦉 Updates from OwlBot post-processor

See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md

* docs(samples): Added GetProcessor Sample

- Also removed extra test function call

* docs(samples): Addressed unit test issues

* docs(samples): Adjusted imports to resovle presubmit errors
