Use infrared requirements as contraints
Use infrared requirements as contraints

When testing it will use infrared requirements as
constraints for octario.

Solves the problem that octario was running using
Ansible 2.6.0 when infrared requirements were >=2.4.0,<2.4.4

Avoids having to always sync requirements with infrared.
