At the end of a job or a job group, you can execute triggers based on the
outcome of the job. The basic format is (in JSON):

    {
        "action": "trigger type",
        "condition": "when to execute this trigger",
        [...action-specific configuration...]
    }

Or in YAML:

    triggers:
      - action: trigger type
        condition: when to execute this trigger
        ...action-specific configuration...

Condition may be one of the following:

- **always**: execute the trigger after every build
- **failure**: execute the trigger after a failed build
- **success**: execute the trigger after a successful build

The following actions are available:

## email
