Add hook scripts for the Jenkins job for Tricircle tempest

1.What is the purpose of this patch set?
The Tricircle project doesn't provide integration test yet.
To achieve integration test, the Tricircle needs to provide
hook scripts for the Jenkins job to execute the test. The Tricircle
integration test Jenkins job will be configured in

https://github.com/openstack-infra/project-config/tree/master/jenkins/jobs

A Jenkins job patch will be submited to project-config once
this patch is merged. Without the hook scripts provided in this
patch, the Jenkins job configured in project-config is not able
to be executed successfully.

After the autotimc Jenkins job is established, all new patches
sumitted to the Tricircle should pass the integration test, i.e. the
test is also the gate test for a new patch.

For example, for cinder volume type patch, currently no integration
test is provided, we don't know the patch work or not.

As new features added to the Tricircle, integration test cases from
the Tempest for OpenStack Nova/Cinder/Neutron could be added to the
post_test_hook.sh, to test the features added to the Tricircle is
correct or not.

2.What is the benefit of this patch set for the Tricircle project?
Reuse OpenStack Nova/Cinder/Neutron tempest test cases, and provide
integration gate test for new patches.

3.What is the platform you tested it out?
After the Jenkins job patch is merged, the test will be executed in
the OpenStack CI pipeline, and as one of the gate test for a new
patch. CI pipeline will be triggered by gerrit review process, and
the test will be executed in the devstack VM(booted by CI pipeline).
