[WIP] Using Http Laravel client instead of Curl

[adeildo-jr]

As discussed in #145, this will replace Curl client with Http client from Laravel. There's many advantages to use Http client.

All idea and code that I'm using goes to hailwood, as he published his custom job using Http client.

I'll describe later all breaking changes from this, as it is a WIP.

Right now, my only concern is about to send XML or other content such as plain/text.

Any advice is welcome.
