The Trigger Agent will watch for a specific value in an Event payload.

The `type` can be one of #{VALID_COMPARISON_TYPES.map { |t| "`#{t}`" }.to_sentence} and compares with the `value`. Note that regex patterns are matched case insensitively. If you want case sensitive matching, prefix your pattern with `(?-i)`.
The `value` can be a single value or an array of values. In the case of an array, if one or more values match then the rule matches.
The `value` can be a single value or an array of values. In the case of an array, all items must be strings, and if one or more values match, then the rule matches. Note: avoid using `field!=value` with arrays, you should use `not in` instead.
By default, all rules must match for the Agent to trigger. You can switch this so that only one rule must match by
setting `must_match` to `1`.
