    Attempts have been made to correct repository namespaces and
    hostnames based on simple pattern matching, but it's possible some
    were updated incorrectly or missed entirely. Please reach out to us

    questions you may have.
    
  - Ensure that global-requirement-pins.txt is applied
    
    In the previous repo build process, we had global constraints which
    override upper constraints and anything set in the roles. This was
    essential for two purposes:
    
    1. To enable us to pin things that were not in upper constraints. eg: pip,
       setuptools, wheel
    2. To enable us to pin things which were in upper constraints, but broken.
       This would usually be a temporary measure until upper constraints was
       fixed.
    
    This patch extracts the global pins from global-requirement-pins.txt
    into a list and sets 'venv_build_global_constraints' to the resulting
    list so that it is applied to all venvs built.
    
    In order to reliably find this file without using a hard-coded path, we
    implement a change to the wrapper script to set the path in it in a
    similar manner to that implemented for the inventory path.
