docs: Executes the request by invoking the wrapped callable unless the call
  has already {@link #isExpired() expired}. If the call is expired or
  throws an exception while being executed, an appropriate message
  is logged out, including the {@link #requestDescriptor request descriptor}
  this instance was created with.
