  - Update prepare-functest role for k8s and fix fetching xci.env

    This change updates prepare-functest role for testing k8s scenarios
    using functest healthcheck. The changes include
    - update tasks to skip checking/creation of public gateway which
    is needed for OpenStack based scenarios
    - update run-functest.sh.j2 template and set the used docker image
    name based on FUNCTEST_SUITE_NAME that is going to be used
    - update run-functest.sh.j2 template and add commands needed to run
    tests using functest-kubernetes-${FUNCTEST_SUITE_NAME} docker image
    - update env.j2 to exclude setting the var EXTERNAL_NETWORK which is needed
    for OpenStack based scenarios

    Apart from updating the the prepare-functest role, a bug has also been fixed
    by adding the fetching of xci.env for installer kubespray.

    installer-type:kubespray
    deploy-scenario:k8-nosdn-nofeature

  - Set additional variables for functest

    CI_LOOP, NODE_NAME, and BUILD_TAG are needed for logging info to console.
    FUNCTEST_MODE and FUNCTEST_SUITE_NAME are important for stating what level
    of testing we do for verify and merge jobs.
