1. Proposed title of this feature request
-> [RFE]Cannot add config_group to hostgroup via API

3. What is the nature and description of the request?  
"As per internal table structure and can see that hostgroup is linked with puppet_class and puppet_class is linked with config_group.

Currently there is now way to link hostgroup with config_group.

This will qualify for a new RFE for API support to add config_group in hostgroup."

----
Not able to see how to assign a config_group to a host or host_group in the API.

When I did it via WebUI, it seems to me the host_group is linked with the puppetclasses rather than the config_group. e.g:

GET https://<foreman>/api/v2/config_groups/1

{
"id": 1,
"name": "rbs-puppet-run",
"created_at": "2016-03-10T16:01:54Z",
"updated_at": "2016-03-11T13:18:33Z",
"puppetclasses": [ {
"id": 497,
"name": "cis::el7all",
"module_name": "cis"
}
]
}

GET https://<foreman>/api/hostgroups/12

{
"name": "rhel7-snp-client-dev",
"id": 12,
"subnet_id": null,
"operatingsystem_id": 1,
"domain_id": null,
"environment_id": 27,
"ancestry": null,
"parameters": {
"kt_activation_keys": "ak-ccv-rhel7-snp-client-dev"
},
"puppetclass_ids": [

]
}
