[FEATURE REQUEST] merge the httpexpect fork into the gavv project

[come-maiz]

The https://github.com/gavv/httpexpect project is actively maintained.

Can you please propose your changes back into the original project?

Hello @come-maiz, there is a reason these projects are splited. The gavv/httpexpect contains big and heavy dependnecies which are not required for Iris at all, the iris-contrib/httpexpect contains only the code Iris needs to be tested. Our fork has the latest features of the original project, so you should be OK.
