Add shortcuts for defining authentication in a recipe

[LucasPickering]

For now only Basic and Bearer auth are supported, but more can be added later. Closes #110

I couldn't get this to work
I have

  rest_call:
    method: GET
    ignore_certificate_hosts: ["www.host.com", "1.2.3.4"]
    authorization: !basic
      username: "{{username}}"
      password: "{{password}}"
    url: "{{base_url}}/rest/call/path"

But I still get a 401 back

Looking at tcpdump I cannot see an Authorization header

@snaggen This feature isn't released yet, just merged to master

[snaggen]

Well, I was compiling and testing master

[LucasPickering]

@snaggen The field is authentication, not authorization

[snaggen]

Ahh... I was just taking the snippet from the linked issue....
Now I get the header, but it is wrong:
authorization: YABpdXjiKpsrlcjp2OE4zQnlMhMWno
should be
authorization: Basic YABpdXjiKpsrlcjp2OE4zQnlMhMWno

Oops! Thank you for testing, I did this in a hurry and got sloppy. I'm in the process of writing tests for this because I forgot to in the original MR, I'll try to get it fixed today.
