make a gauntlt integration with jerry-curl

[wickett]

I think supporting jerry-curl would be great for gauntlt. The key is thinking how you separate work with jerry-curl per project. Something like this

Given I have jerry-curl installed
And I have the following jerry-curl config:
"""
BASE=http://example.com
-include
-H Accept: application/json

Then I should get:

We might want to make this more generic for the When statement. Could be something like this:

Given I have the following profile:
| name | value |
| curl-options | something |
| url_path | /v2/login |
When I run jerry-curl...

@karthequian and @mtesauro what do yall think? This could be cool. Once you have a jerry curl attack or setup that is rigged for an API, you could easily move around and gauntlitze it...
