// Creates a state machine. A state machine consists of a collection of states that
// can do work (Task states), determine to which states to transition next (Choice
// states), stop an execution with an error (Fail states), and so on. State
// machines are specified using a JSON-based, structured language. For more
// information, see Amazon States Language
// (https://docs.aws.amazon.com/step-functions/latest/dg/concepts-amazon-states-language.html)
// in the AWS Step Functions User Guide. This operation is eventually consistent.
// The results are best effort and may not reflect very recent updates and changes.
// CreateStateMachine is an idempotent API. Subsequent requests won’t create a
// duplicate resource if it was already created. CreateStateMachine's idempotency
// check is based on the state machine name, definition, type, LoggingConfiguration
// and TracingConfiguration. If a following request has a different roleArn or
// tags, Step Functions will ignore these differences and treat it as an idempotent
// request of the previous. In this case, roleArn and tags will not be updated,
// even if they are different.
