[BUG] localhost will be replaced by ::1

[Adrian Preuß]

**Version:** `"mysql": "^2.18.1"`

Connection is not opened correctly. Instead of the host name `localhost` is automatically replaced by `::1`.

# Code
```javascript
import MySQL from 'mysql';
import Config from '/opt/Configuration/server/config.json' with { type: 'json' };

constructor() {
this.Connection = MySQL.createPool({
connectionLimit: Config.Database.CONNECTIONS,
host: Config.Database.HOSTNAME,
port: Config.Database.PORT,
user: Config.Database.USERNAME,
password: Config.Database.PASSWORD,
database: Config.Database.DATABASE,
charset: Config.Database.CHARSET,
timezone: 'Europe/Berlin',
queryFormat: (query, values) => {
if(!values) {
return query;
}

return query.replace(/\:(\w+)/g, (txt, key) => {
if(values.hasOwnProperty(key)) {
return MySQL.escape(values[key]);
}

return txt;
});
}
});
}
```

# JSON-Config
```json
{
"Database": {
"HOSTNAME": "localhost",
"PORT": 3306,
"CONNECTIONS": 5,
"DATABASE": "chatservers",
"USERNAME": "chatservers",
"PASSWORD": "*****PASSWORD*****",
"PREFIX": "cs_",
"CHARSET": "utf8mb4"
}
}
```

# JSON-Test
```
console.log(Config.Database.HOSTNAME);

Output: localhost
```

# Result

[Adrian Preuß]

The Problem was on MySQL-Server (MariaDB).

If the Option

```
# Broken reverse DNS slows down connections considerably and name resolve is
# safe to skip if there are no "host by domain name" access grants
skip-name-resolve = ON
```

is enabled, the connection will failed on Handshake.

It is possible to add these to the docs?
