The kayobe-env script does not update the KOLLA_SOURCE_PATH and
KOLLA_VENV_PATH variables if they are already set.  This can lead to
dangerous and difficult to diagnose issues where Kayobe uses a different
version of Kolla Ansible than expected.

This change updates these variables each time the kayobe-env script is
sourced.

Update the URL to the upper-constraints file to point to the redirect
rule on releases.openstack.org so that anyone working on this branch
will switch to the correct upper-constraints list automatically when
the requirements repository branches.

Until the requirements repository has as stable/2024.1 branch, tests will
continue to use the upper-constraints list on master.
