Fix For: 2.1.0
Tasks that needs to be done as part of this ticket:
# Create model for Metrics. Attributes to capture in the model is name,
widget_id, service_name, component_name, type, temporal, pointInTime and level.
All of these are available from API response

# On transition from step-1 "Choose Type" to "Metrics & Expression" page, map
Metrics model from API response of following call
{code}/api/v1/stacks/HDP/versions/2.2/services?artifacts/Artifacts/artifact_name=metrics_descriptor&StackServices/service_name.in(HDFS,HBASE,YARN)&fields=artifacts/*{code}.
*NOTE: Replace HDFS,HBASE, YARN in the above call with the names of all
installed services in the cluster. This API call is implemented in the backend
and is currently working on the current trunk bits.
NOTE: This task needs to be implemented for GAUGE, NUMBER and GRAPH widget
type. Achieving this for TEMPLATE widget type will be achieved in a seperate
task
