The cinder lower constraints CI doesn't work well

[Yikun Jiang]

The actual target of openstack-tox-lower-constraints is used the lower version package to run unit test.

But in Cinder CI,there was a hard code [1] to specify the upper-constraints.txt, that means we first install the package in upper-constraints.txt [2], the lower-constraints.txt doesn't work well.

The right thing is only install the lower in lower-constraints.txt to keep the package as lower version.

    Make lower constraints CI works well

    The actual target of openstack-tox-lower-constraints is using the lower
    version package to run unit test.

    But in current Cinder CI,there was a hard code to specify the
    upper-constraints.txt, that means we install the package in
    upper-constraints.txt, but the lower-constraints.txt doesn't work well.

    This patch try to fix this error, move the hard code to 'deps'.

    We also refresh the lower-constraints.txt and requirements.txt to make
    CI works well:
    1. Add libxml2-dev, libxslt-devel, libxslt1-dev to bindep.txt to make
    lxml can be built successfully, like what we do in other project. [0]
    2. Upgrade oslo.messaging to 6.4.0 to avoid "ACCESS_REFUSED
    - Login was refused using authentication mechanism AMQPLAIN." error.
    3. Upgrade oslo.utils to 3.34.0 to add a new method escape_ipv6 [1] to
    oslo_utils.netutils, which is needed by [2].
    4. Upgrade keystoneauth1 to 3.7.0 to fix "no such option split_loggers
    in group [service_user]" [3]
