Change how type is stored in an enrich policy. (#45789)
A policy type controls how the enrich index is created and
the query executed against the match field. Currently there
is a single policy type (`exact_match`). In the near future
more policy types will be added and different policy may have
different configuration options.

For this reason type should be a json object instead of a string field:

```
{
   "exact_match": {
      ...
   }
}
```

instead of:

```
{
  "type": "exact_match",
  ...
}
```

This will make streaming parsing of enrich policies easier as in the
new format, the parsing code can know ahead what configuration fields
to expect. In the latter format that is not possible if the type field
appears not as the first field.
