A list of metric definition objects. Each object specifies the metric name and regular expressions used to parse
algorithm logs. SageMaker publishes each metric to Amazon CloudWatch.

@param metricDefinitions
       A list of metric definition objects. Each object specifies the metric name and regular expressions used to
       parse algorithm logs. SageMaker publishes each metric to Amazon CloudWatch.
@return Returns a reference to this object so that method calls can be chained together.
