Note:
The OpenTracing API defines the values of *key_values* to be of any
type. However, the OpenTelemetry API requires that the values be
any one of the types defined in
``opentelemetry.trace.util.Attributes`` therefore, only these types
are supported as values.
Args:
key_values: A dictionary as specified in
``opentelemetry.trace.util.Attributes``.
timestamp: Timestamp of the OpenTelemetry event, will be generated
automatically if omitted.
Returns:
Returns this :class:`SpanShim` instance to allow call chaining.
