Pin heat-tempest-plugin to good hash

heat-tempest-plugin post [1] requires python-gabbi
to be updated to 1.49.0 and wsgi_intercept
to 1.9.2. Both of these are updated for CentOS8
already and jobs are passing with it, considering
CentOS7 will be removed soon avoiding the updates
for these deps for centos7, so proposing pinning
of heat-tempest-plugin to a commit which do not
need updated deps.
