We want to remove the map type, but doing that is a larger operation. To get the user-facing breaking change out earlier, i.e., in time for 3.0, we're just making it inaccessible first and are then removing it later on.
This was the only place in VAST that ever used the map type for table
slices written to disk: The `vast.metrics` event, whose metadata was
never queryable.
Now, behold the beauty of actually queryable metrics from the self-sink:
```
$ vast -qq export json '#type == "vast.metrics.passive-store.init.runtime"
| select ts,value
| summarize min(value), max(value) by ts resolution 10s'
{"ts": "2023-02-28T17:21:50.000000", "min(value)": 0.218875, "max(value)": 107.280125}
{"ts": "2023-02-28T17:20:00.000000", "min(value)": 0.549292, "max(value)": 0.549292}
```
To enable the self-sink for testing, set the following:
```yaml
# <prefix>/etc/vast/vast.yaml
vast:
enable-metrics: true
metrics:
self-sink:
enable: true
```

Loving the "self sink" example! |
