/**
  <code>MetricDimension</code> is a subproperty of the <code>CloudWatchAlarmDefinition</code> property type. <code>MetricDimension</code> specifies a CloudWatch dimension, which is specified with a <code>Key</code> <code>Value</code> pair. The key is known as a <code>Name</code> in CloudWatch. By default, Amazon EMR uses one dimension whose <code>Key</code> is <code>JobFlowID</code> and <code>Value</code> is a variable representing the cluster ID, which is <code>${emr.clusterId}</code>. This enables the automatic scaling rule for EMR to bootstrap when the cluster ID becomes available during cluster creation.
