monkey patch to support socks proxy

[realByg]

according to this issue #2541, the support of socks proxy is possible but only throught env var
So I manage to whip up some dodgy code to get it working

from urllib3.contrib.socks import SOCKSProxyManager
from botocore.httpsession import URLLib3Session, ProxyConfiguration
from botocore.awsrequest import AWSConnection

_aws_connection_init = AWSConnection.__init__


def aws_connection_init(*args, **kwargs):
	kwargs.pop('_socks_options', None)
	_aws_connection_init(*args, **kwargs)


AWSConnection.__init__ = aws_connection_init

ProxyConfiguration._fix_proxy_url = lambda self, s: s

def _get_proxy_manager(self, proxy_url: str):
        if proxy_url not in self._proxy_managers:
	        proxy_manager_kwargs = self._get_pool_manager_kwargs(
		        **self._proxies_kwargs(
			        proxy_ssl_context=self._setup_proxy_ssl_context(proxy_url)
		        )
	        )
	        proxy = urlparse(proxy_url)
	        if proxy.scheme in ('http', 'https'):
		        proxy_manager_kwargs['proxy_headers'] = self._proxy_config.proxy_headers_for(proxy_url)
		        proxy_manager = ProxyManager(proxy_url, **proxy_manager_kwargs)
	        elif proxy.scheme in ('socks4', 'socks5'):
		        proxy_manager_kwargs['username'] = proxy.username
		        proxy_manager_kwargs['password'] = proxy.password
		        proxy_manager = SOCKSProxyManager(proxy_url, **proxy_manager_kwargs)
	        else:
		        raise Exception(f'proxy url {proxy_url} scheme unknown')
        
	        proxy_manager.pool_classes_by_scheme = self._pool_classes_by_scheme
	        self._proxy_managers[proxy_url] = proxy_manager
        
        return self._proxy_managers[proxy_url]

URLLib3Session._get_proxy_manager = _get_proxy_manager

is there a better way to do this?
