Hey,  
we have a problem here.  
After we make a PUT mapping, it removes our `_meta` Field from the mapping.  
Is this normal? Can we prevent this?

Bevore:

```auto
{
    "foo": {
        "mappings": {
            "bar": {
                "_meta": {
                    "foo": "bar"
                },
                "properties": {
...

```

After:

```auto
{
    "foo": {
        "mappings": {
            "bar": {
                "properties": {
...

```

Sample Request:

```auto
PUT /foo/_mapping/bar HTTP/1.1
Content-Type: application/json
Host: xxx
X-Amz-Date: xxx
Authorization: xxx

{  
 "properties":{  
 }
}

```

We running on version 2.3 on AWS

Thanks helping me,
