feat(http): set http options globally

New feature allows users to configure their HTTP options with
classic environment variables (e.g. http_proxy, https_proxy,
no_proxy). Additionally, allows users to ignore SSL verification
if uploading certificates for every use case is not practical.

- Fixes #191
- Fixes #192
