Provide option to increase the keep alive timeout for Robyn

[LohithBlaze]

• How is this important to you? How would you use it? We are using Robyn as a microservice in order to send out events from various services to other services. Hence in order for faster event processing. We want increase the keep alive timeout for TCP connection to keep the active for connection pool to keep the connection

• Can you think of any alternatives? Right now only option is to use it as is

• Do you have any ideas about how it can be implemented? Are you willing/able to implement it? Do you need mentoring? Yes if needed I can start contributing. Basically I'm assuming there will be a config to increase the timeout.
