Add cnf-conformance in functest-kubernetes-cnf
It selects cnf-conformance v0.7.2-beta1 (current latest release) and the default CNF as proposed by [1]. The end user is free to override the default yml files on purpose (e.g. docker volumes). Tag (default: all) could be modified too via testcases.yaml [1] https://hackmd.io/@vulk/SkY54QnsU Change-Id: Iec2a830c441e523e067f6eb114ecb205c49c6b93 Signed-off-by: Cédric Ollivier <cedric.ollivier@orange.com>
