Description of problem:
Using the hammer CLI to create discovery rules fails with an error related to missing organizatrions_id.  Hammer is not passing along the default organization ID nor are command line options documented that allow specifying this.

Discovery rules cannot be created without tying to a specific organization ID.

Version-Release number of selected component (if applicable):
Satellite version 6.2.9
Hammer version 0.5.1.13

How reproducible:
Always.

Steps to Reproduce:
1. hammer -d discovery_rule create --hostgroup $hostgroup --name MyDiscoveryRule --search "organization = lab"
2. 
3.

Actual results:
Returns http 422 error "Organizations Host group organization lab must also be associated to the discovery rule"

Expected results:
Discovery rule created.

Additional info:

Run in debug I see the following params provided in the API POST request:
    "discovery_rule" => {
                "name" => "MyDiscoveryRule",
              "search" => "organization = lab",
        "hostgroup_id" => 2
    }

If I run the following direct API query the discovery_rule is created since the organization_ids are provided.

curl -X POST -H "Accept:application/json,version=2" -H "Content-Type:application/json" -s -k -u user:password -d "{\"name\":\"MyDiscoveryRule\", \"search\":\"organization = lab\",\"hostgroup_id\":2, \"organization_ids\": [1]}" https://satelliteserver/api/v2/discovery_rules
