Return of AnsibleTower workflows and job-templates should include inventory and description

[bherrin3]

Problem

• There are now MANY inventories that exist for users to deploy and the default inventory may not be the correct location to deploy (they may want to override run-time)
• By default, the description of the workflow / job-template (which is in the API) is not passed back to the user when requesting information about a workflow / job-template

Solution

• Add both of these as a return to the following

(broker) ➜  broker git:(master) ✗ broker providers AnsibleTower --workflow deploy-base-rhel
[INFO 230217 10:48:36] Querying provider AnsibleTower

[INFO 230217 10:48:40] Accepted additional nick fields:
    deploy_scenario: baserhel
    deploy_rhel_version: ''
    host_type: host 

(broker) ➜  broker git:(master) ✗ broker providers AnsibleTower --job-template satlab-tower-set-swap

Just FTR, broker is still not able to choose the instance of AnsibleTower to get the WF/JT details from. See #127
