Constrain 'robotframework-requests' to versions <0.8.0
Constrain 'robotframework-requests' to versions <0.8.0

Robotframework request API was changed in a version 0.8.0.
It is not possible to use the newest version with the current
openbmc-test-automation codebase.
Therefore constrain 'robotframework-requests' version to <0.8.0.
