Add a new alert node property method to match all points to reset alert.

Based on discussion on #1859, I'd like to suggest to add a feature.

Alert node needs a property method which matches all points to reset alert.

So all points should be matched to reset the alert not just 1 of them.
Simply it equivalents `.all` property method but for resting the alert.

For example, in some use cases when the joined sources have more than 1 point, it will be hard to join min as a single point.

```
var threshold = 80

// This returns 5 points.
var source01 = batch
|query('''
SELECT percentile("used_percent", 95.0) AS "used_percent"
FROM "telegraf"."autogen"."mem"
''')
.groupBy(time(1m), 'host')
.period(5m)
.every(2m)
.fill('none')

// This returns 1 point, which is the `min` point in 5 min.
var min = source01
|min('used_percent')
.as('used_percent')
|window()
.period(1m)
.every(1m)

// This returns 1 point, which is the `max` point in 5 min.
var max = source01
|max('used_percent')
.as('used_percent)
|window()
.period(1m)
.every(1m)

var data = min
|join(max)
.as('min', 'max')
|eval(lambda: "min.used_percent", lambda: "max.used_percent")
.as('used_percent_min', 'used_percent_max')
|alert()
.warn(lambda: "used_percent_min" > threshold)
.warnReset(lambda: "used_percent_max" < threshold)
```

As you see here, on one hand, that needs more work to be achieved, and on the other hand, not all points are included in the alert (we here just have 2 point out of 5)

My suggestion is something exactly like `.all()` property method but for reset.

```
var threshold = 80

// This returns 5 points.
var source01 = batch
|query('''
SELECT percentile("used_percent", 95.0) AS "used_percent"
FROM "telegraf"."autogen"."mem"
''')
.groupBy(time(1m), 'host')
.period(5m)
.every(2m)
.fill('none')
|alert()
.all()
.resetOnAll()
.warn(lambda: "used_percent" > threshold)
```

Thanks.

Start with the alert node and its existing .all() property method, then trace how warnReset handles joined points. Compare the proposed resetOnAll() behavior against the example's five-point stream; done means all points must satisfy the reset condition before the alert resets, with coverage for the multi-point case.
