http_helper package is covering HTTP GET methods only and doesn't allow to send HTTP Headers

[sw-samuraj]

The http_helper package currently supports the HTTP GET method only. Additionally, it doesn't allow to send any HTTP Header.

Questions:

1. Is it planned to support other HTTP methods, e.g. POST?

2. Is it planned to support HTTP Headers? This could be important if a service expects some mandatory headers, e.g. a token etc.

We add methods when we use them. So far, most of our tests have needed GET and no headers, but if you have a use case that needs more, I'd definitely welcome a PR to add those!
