Provide C# code examples for APIs

[kyyberi]

What is the problem?

We don't have any C# code examples for the API endpoints. Each endpoint should have a simple example of how to use endpoint.

What do you expect to see / happen?

All the methods in all endpoints have placeholders for code examples in markdown files in folder https://github.com/PlatformOfTrust/docs/tree/master/raml2markdown/examples

Provide C# code examples for each endpoint and make a PR. Set @kyyberi as a reviewer.

C# code examples must be written inside

"```csharp
example here...
```"

Acceptance criteria:

• Code examples work in Sandbox. Test your code examples in the sandbox environment.
• Add includes are in the examples too.
• Uses commonly used libraries to handle API requests and JSON responses.
