cli handler fails to report/substitue the limit_value field

Hi,
While trying to setup the cli to hit a custom webhook, found that the limit_value is not being reported on the alert.

example alert rule: ['warning: < 10000 OR > 15000', 'critical: > 20000']

Start by locating the CLI handler and the custom webhook alert-formatting path. Reproduce the example rule with warning and critical limits, then trace how limit_value is substituted or reported. Done means the resulting webhook alert includes the applicable limit_value for the triggered condition.
