The commit adds a support for template function `query`, `first` and `value`. The function `query` executes a MetricsQL query for active alerts. In vmalert we update templates on every evaluation for active alerts to keep them up to date. With `query` func it may become a perf issue since it will fire a query on every execution. We should keep it in mind for now. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/539
