/// An interceptor allows injecting code into the SDK ’s request execution pipeline.

/// ## Terminology:
/// - An execution is one end-to-end invocation against an SDK client.
/// - An attempt is an attempt at performing an execution. By default executions are retried multiple
///   times based on the client ’s retry strategy.
/// - A hook is a single method on the interceptor, allowing injection of code into a specific part
///   of the SDK ’s request execution pipeline. Hooks are either "read" hooks, which make it possible
///   to read in-flight request or response messages, or "read/write" hooks, which make it possible
///   to modify in-flight request or output messages.
