The apache mod_proxy documentation[0] says that trailing slashes need to
match for the ProxyPass statement. Since adding a slash to the redirected
url would break things that need to access endpoints like /identity
without anything added, we need to drop the trailing slash for the
target URL. See [1] for the discussion of the CVE fix that changed the
previous behavior.
For stable/victoria the devstack-platform-opensuse-15 and
nova-ceph-multistore jobs are currently broken, drop them for now,
they can be re-added when they got fixed.
