Unblock gate to temporary remove the py3.6|7 job

py3.6 and py3.7 jobs are failing due to oslo dropped the
py3.6|7 support. We will add them back once bug#1975036
is resolved

Tempest plugin sanity job is broken due to failure in
murano-tempest-plugin. To make this patch merge which
will unblock the gate, I am making plugin sanity job as
non voting. We will revert that once below fix is merged

tempest-full-centos-9-stream job is also failing which fix
is also up and waiting for this patch to merge first, so making
them non voting.

devstack-plugin-ceph-tempest-py3 job is also mostly failing, let's
make it temporarily non voting in order to avoid endless rechecks
