GraphQL: command operationId can be null, and queued command statuses
CommandExecution.operationId on the public GraphQL API can now be null until the command is sent. CommandStatusType includes QUEUED and QUEUED_CANCELLED.
If your client was generated when operationId was non-null (String!), treat it as optional. The identifier is absent until the command is sent.
CommandStatusType now includes:
QUEUEDQUEUED_CANCELLED
Clients that match on every command status should handle these values.
