Metric
Every Monitor can send Metrics to Nursery ecosystem. This domain is responsible for Y axis of the graphs dashboard.
A monitor is responsible to N metrics, for example, MemoryMetric, CPUMetric, IOMetric, AccessMetrics, and so on.

For now, a Metric has the following attributes:

• Monitor: the monitor that is sending this Metric.
  -- This monitor should be on RUNNING status to have granted access for publishing Metrics.
• ID (8~32 String)
• Name: Probably the Y axis name on graphs dashboard (Example: Memory)
• Type: Identifies what is the MetricData type. For now, it only accepts SingleValuedData.
  • MetricData #9
• TimeInterval: The time (in minutes) that the monitor will send MetricData for this Metric
