Jesse Pretorius f438c65028 Move upper constraint logic to after python is installed
Currently if python is not already installed on the deployment host
the bootstrap-ansible script fails due to the way that the script
tries to check the python version installed (using python to do it).

This patch moves the logic until after python is actually installed
to cater for the situation where it may not already have been.
