-------------------------------------

             Summary: Create ember data model for widget
                 Key: AMBARI-10102
                 URL: https://issues.apache.org/jira/browse/AMBARI-10102
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 2.1.0


As a part of this ticket, create an experimental flag under which poll for =
the widget information from the stack while landing on the service summary =
page for the first time. Since this is a static information, it is required=
 to be polled just once. This needs to be mapped to a model as described be=
low

Example API for HDFS service:
{code}
{
  href: "http://c6401.ambari.apache.org:8080/api/v1/stacks/HDP/2.2/services=
/HDFS/artifacts/widget_layout",
  Artifacts: {
    artifact_name: "widget_order",
    service_name: "HDFS",
    stack_name: "HDP",
    stack_version: "2.2"
  },

 artifact_data: {
       name: "HDFS",  // This is the serviceName in the ember-data model
       sections: [=20
         {
           name: "HDFS_SUMMARY" // This is the sectionName as described in =
the below ember-data model
           widgets: [
             {
               widget_name: =E2=80=9CNAMENODE_HEAP=E2=80=9D,

               }
             },=20
             {
