Add support for Proxies

[pranitbauva1997]

I have to use sendgrid to send newsletter mails. Being under a institute proxy, I have to SSH into a AWS server and then pull my script+data there and then send my mails from there.

Now I understand this feature isn't that a big improvement, but this would really help me. I want to make this fix in this package.

What are your opinions?

Go for it!! If this is something that you need, someone else might need it to. Please make a PR of your change, so long as it is documented, configurable, testable, and passes our build and testing - we will get it merged in.

I guess this would need ProxyHandler added in python_http_client first or at the same time, right?
https://github.com/sendgrid/python-http-client/blob/master/python_http_client/client.py

Would the intention be to add proxies kwargs when instatiating SendGridAPIClient ? And then pass the kwargs through to python_http_client Client?

Hi @campbellmc,

Yes, that is correct. Thanks!
