feat: Add readTimeout and conenctionTimeout as configurable parameters

[hmhuan]

I got the issue like below so I would like to contribute to fix it by apply configurable for connectionTimeout and readTimeout.

stack_trace: java.io.IOException: ailed to push metrics to the Prometheus Pushgateway on <pushgateway_address>: Read timed out
Caused by: java.net.SocketTimeoutException: Read timed out

• AS-IS: the current connectionTimeout and readTimeout is 10s
• TOBE: we can create builder with connectionTimeout and readTimeout custom value, default value is 10s
