Hi,

Running on 7.10.2.  
I have added the "Apache" integration to collect only logfiles, not metrics.  
When I go to discover to browse the logs-\* index, these errors appear:

```auto
1 of 8 shards failed
## illegal_argument_exception at `shard` 0 `index` .ds-logs-apache.access-default-000001 `node` 30iScyvDQLG7jd-CklbUhw
Reason
Field [event.created] of type [keyword] does not support custom formats

```

The request shows:

```auto
    {
      "field": "event.created",
      "format": "date_time"
    },

```

Never mind.  
When I create a new index pattern for the log-apache.access & log-apache.error data streams, it works fine.

I think you might find a bug here. I don't think the event.\* fields are added into the apache package. I will look into this. Thank you!
