[backport/2.2] Move integration test suite from molecule to ansible-test (#392) (#457)

[backport/2.2] Move integration test suite from molecule to ansible-test (#392)

Move integration test suite from molecule to ansible-test
SUMMARY
molecule has been replaced with ansible-test
some test cases have been updated
k8s_apply : remove duplicated tasks increasing the running time of the test
helm: use different namespaces for different test cases in order to wait for the namespace deletion before moving to the next test.
all: remove wait: yes at the end of each test when deleting namespace, the role used to create namespace will ensure that it is deleted before if existing.
