Pass global set proxy settings to mongodb-download

[thisispax]

This pull request passes the global set proxy settings to mongodb-download. So as mentioned in this issue (#20) a download through a corporate proxy will be possible.

mongodb-download allows you to pass opts, to that you can pass agent and your own proxy object

mongoose uses mongodb-prebuilt to get mongodb. but that doesn't work for me because of our proxy... so what would you suggest to do?

@pax1878 👍

Please merge @winfinit

Having exactly the same problem as @pax1878 - The npm install for mongodb-prebuilt automatically calls mongodb-download, without the ability to pass in the opts anywhere. @pax1878 's code solves this by using the system-wide proxy environment variable.

Please accept the pull as it will only impact those with the proxy variable set and works well in our testing.

@BenCoffman and @pax1878, I've released new version of Mockgoose 6.0.0 there are small modifications to your unit tests that you would have to do, but it will save you a lot of headache in the future, if you will convert to 6.0 release, that also incorporates requested feature here.
