Aws-cdk: Cannot call request validator options multiple times.

[durja]

Calling the constructor for RequestValidatorOptions multiple times gives an error

There is already a Construct with name 'validator' in RestApi

Reproduction Steps

`

    resource1.add_method(
        http_method='POST',
        integration=xxxIntegration,
        request_parameters={
            'method.request.header.passcode': True,
            'method.request.header.message': True
        },
        request_validator_options=_apigw.RequestValidatorOptions(validate_request_parameters=True, request_validator_name='POST-r1-validator')
    )

    resource2.add_method(
        http_method='POST',
        integration=yyyIntegration,
        request_parameters={
            'method.request.header.passcode': True,
            'method.request.querystring.id': True
        },
        request_validator_options=_apigw.RequestValidatorOptions(validate_request_parameters=True,request_validator_name='POST-r2-validator') 
    )

`

Thanks for filing this @durja. This is, in fact, a bug on the CDK.

You can workaround this by using the requestValidator property.
