Requesting the addition of three fields.

rule_id: (string, optional, default empty) Arbitrary rule ID defined by the rule author. Most common rule frameworks have the concept of a rule ID and leverage some kind of numeric or alphanumeric range.

reference: (string or list of strings, optional, default empty) Arbitrary external reference link(s). Common use case here is one or more hyperlinks to external rule documentation, or to provide outside context pertinent to the rule.

description: this field already exists, but is not available to built-in alerter types. It should be.

Each of these three fields should be present in the elastalert events, as well as available for inclusion in the built-in alerter types.
