How to test this: you can use MinIO and firewall tools on Mac to
artificially limit your network connection.
1. Setup a MinIO server (default port is localhost:9000), make a bucket and
put a simple text file in it.
2. Now change your network connection to 9000 to add a 10s delay each way by
doing the following:
```
sudo dnctl pipe 1 config plr 0.3 bw 100Kbit/s delay 10000
echo "dummynet in proto tcp from any to localhost port 9000 pipe 1
dummynet out proto tcp from any to localhost port 9000 pipe 1" | sudo
pfctl -f -
sudo pfctl -e
```
3. telnet 127.0.0.1 9000 should now establish connection after 20s.
4. Now if you don't specify timeout options when making a S3FileSystem in
Python, it will timeout.
5. However if you specify the following options: s3 =
fs.S3FileSystem(access_key="minioadmin",secret_key="minioadmin",endpoint_override='127.0.0.1:9000',scheme="http",connect_timeout_ms=100000,
request_timeout_ms=100000) it will work!
