commands: any? all? (#3252)

* commands: any? all?

We can check if `any` (or `all`) rows of tables match predicates.

Small `all?` example: Given the following table with `services` running:

```
> echo [[status]; [UP] [UP]]
───┬────────
 # │ status
───┼────────
 0 │ UP
 1 │ UP
───┴────────
```

We can ask if all services are UP, like so:

```
> echo [[status]; [UP] [UP]] | all? status == UP
true
```

* Fix any? signature.
