#14325 [csharp] - Add CancellationToken to generated aspnetcore controller methods.

[philkild]

Resolve #14325. The change adds a CancellationToken to all generated aspnetcore controller methods. The change can be verified by updating /bin/configs/aspnetcore-3.0.yaml with the below and generating the samples. Without these settings, the generated samples are unchanged:

  operationIsAsync: true
  operationResultTask: true

The CancellationToken is automatically bound as described in issue #14325 and therefore does not require any other changes and consumers can continue to use the API as normal

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master (6.3.0) (minor release - breaking changes with fallbacks), 7.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.
