Hello @Rohithzr and thank you for the contribution!

The only issue this might have is that it's incompatible with node <= 4. We planned on releasing a node-gyp@4.0.0 that will require node@4, so generally this might need to wait before we land this in master.
Or you can add a bump of the node version as well in:

node-gyp/package.json

Lines 37 to 39 in 50b8734

	"engines": {
	"node": ">= 4.0.0"
	},

Let's see if our CI is properly setup - https://ci.nodejs.org/job/nodegyp-test-pull-request/54/

I guess I was wrong and request>=2.82.1 is only incompatible with node < 4, so we're all good here.

@refack Ben split off a a v3.x branch to continue v3.x releases. For node-gyp@4.0.0 we might as well drop Node.js v4 as well given that it is EOL.

[Rohithzr]

Ah! I actually tested it with node 4.x which is still used somewhere in our legacy code. didn't give me any issues. Thanks for confirming it.

Although the version should match, maybe use 2.87.0 since they removed the heok/hawk issues https://github.com/request/request/blob/master/CHANGELOG.md#v2870-20180521

@refack I guess this PR can be merged now.
the request bump solves security issues while supporting node < 4

FWIW we did this update in node-sass@4.9.1 to resolve the security warnings and maintains support for Node 0.10. It was a smooth update.

@Fishrock123 so it works here without a doubt. How about we merge this and also figure out the 3.x.
