Support for PyMySQL

### Describe the feature

Support the usage of the pymysql connector

### Use Case

The project I'm working on uses pymysql, I tried to pass the `Connect` class to the `AwsWrapperConnection`, however, it's failing because it's casting the port argument to a `string`, even though I'm passing an `int`.

Code that's turning the port into a string:
```
def prepare_connect_info(self, host_info: HostInfo, props: Properties) -> Properties:
prop_copy: Properties = Properties(props.copy())

prop_copy["host"] = host_info.host

if host_info.is_port_specified():
prop_copy["port"] = str(host_info.port)

PropertiesUtils.remove_wrapper_props(prop_copy)
return prop_copy
```

pymysql code enforcing the int type:
`connections.py`
```
// ...
self.port = port or 3306
if type(self.port) is not int:
raise ValueError("port should be of type int")
// ...
```

I wonder if it's possible to remove that cast to string or adapt somehow to support pymysql. I'm not sure if that's all it's going to take, though.

### Proposed Solution

Remove the cast to string for the port
```
if host_info.is_port_specified():
prop_copy["port"] = host_info.port
```

or a condition for the pymysql library

从 prepare_connect_info 开始，跟踪其 port 属性如何传递到 PyMySQL connections.py 的验证逻辑。使用整数端口检查现有的连接流程，并确认支持能够正常工作且不会破坏其他连接器；当 PyMySQL 连接接受配置的端口时，即视为完成。
