[sahara] Failed to copy cluster template

[Yaroslav Lobankov]

Failed to copy cluster template.

Reproduction steps:

1. Create one or a few node group templates.
2. Create cluster template via API request. Cluster template must use IDs of created node group templates and node groups described in cluster template directly. For example, request body for cluster template may be

{
    "name": "some-cluster-template",
    "description": "Some Cluster template",
    "plugin_name": "vanilla",
    "hadoop_version": "1.2.1",
    "cluster_configs": {},
    "node_groups": [
        {
            "name": "master",
            "node_group_template_id": "35c17bf0-d74b-43b4-99b7-a395a6e4b407",
            "count": 1
        },
        {
            "name": "worker",
            "flavor_id": "2",
            "node_processes": ["tasktracker", "datanode"],
            "node_configs": {},
            "count": 2
        }
    ]
}

3. Go to Sahara dashboard. Try to copy cluster template.

Expected result:
Template has been successfully copied.

Observed result:
Template has not been copied.

Error from Horizon is the following:
Error: {u'count': 2, u'name': u'worker', u'node_group_template_id': u'None'} is not valid under any of the given schemas
