Cancel an in-flight request by sending notifications/cancelled for
requestId (basic/utilities/cancellation: "Either side can send a
cancellation notification ... to indicate that a previously-issued request
should be terminated"). After this call, any response the server still
sends for requestId is ignored, per "The sender of the cancellation
notification SHOULD ignore any response to the request that arrives
afterward". reason is an optional free-form explanation included in the
notification when non-empty.
Per spec, the initialize request MUST NOT be cancelled by clients;
attempting to cancel the id of the initialize request throws.
