// Creates an Amazon Web Services Migration Hub Refactor Spaces route. The account
// owner of the service resource is always the environment owner, regardless of
// which account creates the route. Routes target a service in the application. If
// an application does not have any routes, then the first route must be created as
// a DEFAULTRouteType. When created, the default route defaults to an active state
// so state is not a required input. However, like all other state values the state
// of the default route can be updated after creation, but only when all other
// routes are also inactive. Conversely, no route can be active without the default
// route also being active. When you create a route, Refactor Spaces configures the
// Amazon API Gateway to send traffic to the target service as follows:
//
// * If the
// service has a URL endpoint, and the endpoint resolves to a private IP address,
// Refactor Spaces routes traffic using the API Gateway VPC link.
//
// * If the service
// has a URL endpoint, and the endpoint resolves to a public IP address, Refactor
// Spaces routes traffic over the public internet.
//
// * If the service has an Lambda
// function endpoint, then Refactor Spaces configures the Lambda function's
// resource policy to allow the application's API Gateway to invoke the
// function.
//
// A one-time health check is performed on the service when either the
// route is updated from inactive to active, or when it is created with an active
// state. If the health check fails, the route transitions the route state to
// FAILED, an error code of SERVICE_ENDPOINT_HEALTH_CHECK_FAILURE is provided, and
// no traffic is sent to the service. For Lambda functions, the Lambda function
// state is checked. If the function is not active, the function configuration is
// updated so that Lambda resources are provisioned. If the Lambda state is Failed,
// then the route creation fails. For more information, see the
// GetFunctionConfiguration's State response parameter
// (https://docs.aws.amazon.com/lambda/latest/dg/API_GetFunctionConfiguration.html#SSS-GetFunctionConfiguration-response-State)
// in the Lambda Developer Guide. For Lambda endpoints, a check is performed to
// determine that a Lambda function with the specified ARN exists. If it does not
// exist, the health check fails. For public URLs, a connection is opened to the
// public endpoint. If the URL is not reachable, the health check fails. For
// private URLS, a target group is created on the Elastic Load Balancing and the
// target group health check is run. The HealthCheckProtocol, HealthCheckPort, and
// HealthCheckPath are the same protocol, port, and path specified in the URL or
// health URL, if used. All other settings use the default values, as described in
// Health checks for your target groups
// (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/target-group-health-checks.html).
// The health check is considered successful if at least one target within the
// target group transitions to a healthy state. Services can have HTTP or HTTPS URL
// endpoints. For HTTPS URLs, publicly-signed certificates are supported. Private
// Certificate Authorities (CAs) are permitted only if the CA's domain is also
// publicly resolvable.
