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. Change-Id: Iaa5499155b4b94a1cfc6b5c70fe6f8f7417502a6 Signed-off-by: Fatih Degirmenci <fdegir@gmail.com>
