Application Lifecycle Event

[maxhotta]

I'd like to propose adding an Application Lifecycle Event to the Application category.
A discussion point may be whether we'd need additional ID's for the cloud profile (e.g., provision/deploy).

{
  "uid": 2,
  "description": "Application Lifecycle events report installation, removal, start, stop of an application or service.",
  "extends": "application",
  "caption": "Application Lifecycle",
  "name": "application_lifecycle",
  "profiles": [
    "host"
  ],
  "attributes": {
    "$include": [
      "profiles/host.json"
    ],
    "activity_id": {
      "requirement": "required",
      "enum": {
        "1": {
          "caption": "Install"
        },
        "2": {
          "caption": "Remove"
        },
        "3": {
          "caption": "Start"
        },
        "4": {
          "caption": "Stop"
        }
      }
    },
    "product": {
      "description": "The product that initiated the Application Lifecycle activity.",
      "group": "primary",
      "requirement": "required"
    }
  }
}
