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/2025.1 branch, tests will
continue to use the upper-constraints list on master.

Previously, data which may be considered sensitive
such as the X-Auth-Token or X-Storage-Token headers is hidden for
the --info option but not --debug.

This patch enables truncating of LOGGER_SENSITIVE_HEADERS by default for
--debug so that end users can share debug output more easily without
having to manually sanitize logs and adds unit tests for it.

A separate --debug-with-secrets option is provided should explicit
printing of auth tokens be desirable, mimicking the old behaviour.

--debug-insecure, suggested on launchpad naming was considered as well
however a --insecure param which skips SSL verification already exists
and does something else. The --with-secrets suffix should also help
make the purpose of this param explicit enough.
