Add http proxy option for near-cli

[nanbatian119]

Problem: I have to use vpn to connect to rpc.testnet.near.org. But It only takes effect in my browser and bash terminal. In near-cli vpn won't works. I guess nodejs program can't use global proxy bring this problem.

Suggest: Near-cli may add http_proxy option for users in case of direct connect problems.
