dist pull hangs when the network is unavailable for more than 5 mins

Description: While downloading a specific jballerina distribution, I disconnect the internet connection and waited for 5 mins then connected back to internet. Downloading didnt time out or continued after reconnection. It should time out after some time.

➜  bin ./ballerina dist pull jballerina-1.0.1
