Currently functional jobs are all broken because of recent bump of
cinder client. Since we need fix for both heat and heat-tempest-plugin
repo this change first make all functional jobs non-voting to unblock
any change in heat-tempest-plugin repo until the fix is merged in heat.

We have stable/wallaby released so we should add
their job on master gate to keep branchless tempest
plugins compatible to stable branch.

This also removes the stable/stein job as that is in EM
state now.

The repo is Python 3 now but still tests some older
branches, so update hacking to version 2.0 which

Fix problems found.

Due to this typo cert_validate had been recognized as tuple but
not boolean.

stable/ussuri branch is setup now
- https://review.opendev.org/#/q/topic:qa-ussuri-release+status:merged+projects:openstack/devstack

and Tempest and plugins master version is used to test the stable/ussuri.

Adding a stable job for ussuri on master so that any new tests
or changes does not break the stable ussuri testing.

Tempest already added the stable/ussuri job on master gate so adding it
for plugins is safe now.

stable/queens and stable/rocky are in extended maintainance state
and devtack use the older Tempest version to tests them not the master.

Testing them on master gate is not needed as heat-tempest-plugin master
cannot support testing them due to python required version for plugin
and Tempest. Even we test them on master gate, they run with older Tempest
so they are not actually testing the master code against those stable.

We can continue testing the supported stable branch where master Tempest and
plugins are used.

Same is done Tempest and other plugins side:

We have migrated our testing from Xenial to Bionic
since stein. Xenial node is not supported on stein onwards.

Any job running on stein onwards should use the bionic nodeset.

OpenStack is dropping the py2.7 support in ussuri cycle.

heat-tempest-plugin is ready with python 3 and ok to drop the
python 2.7 support.

cannot run py2 jobs on master gate.
