**Use case**

This works:

```
SELECT * FROM hits_100m_obfuscated INTO OUTFILE 'hits.csv' FORMAT CSV
```

But I want this:

```
SELECT * FROM hits_100m_obfuscated INTO OUTFILE 'hits.csv'
```

**Describe the solution you'd like**

Every format can register file extension(s) in format factory.
If format is not specified explicitly, we can detect it automatically by file extension.
It should work for compressed files `hits.csv.gz` as well.

The following extensions should be supported at least:
csv, tsv, parquet, orc, native, json, ndjson, xml, md, avro

**Addition details**

Let's also support omitting the format argument for `file`, `url`, `s3`, `hdfs` table functions. 
if (!name_p.parse(pos, format, expected))
            return false;
        tryGetIdentifierNameInto(format, format_str);
    }
    else if (s_select.ignore(pos, expected) || s_with.ignore(pos,expected))
    {
        
        
        pos = before_values;
        ParserSelectWithUnionQuery select_p;
        select_p.parse(pos, select, expected);
        
        if (s_format.ignore(pos, expected) && !name_p.parse(pos, format, expected))
            return false;
        tryGetIdentifierNameInto(format, format_str);
    }
    else if (s_watch.ignore(pos, expected))
    {
        
        
        pos = before_values;
        ParserWatchQuery watch_p;
        watch_p.parse(pos, watch, expected);
        
        if (s_format.ignore(pos, expected) && !name_p.parse(pos, format, expected))
            return false;
    }
    else
    {
