tests,network: quarantine istio+passt tests

CI runs very old version of Istio that does not support new k8s
features and block development that utilize such features (e.g.: restart
policy for init containers).

The is an effort to upgrade Istio version CI use, but it fails due to
because some Istio+passt tests failing [1].

Turn out VMs who's virt-laucher pod have Multus network annotation in
JSON form doesn't work with newer version of Istio [2].
VM with passt binding plugin produce virt-laucher pod with Multus
network annotation in JSON form.

Quarantine istio+passt failing tests to unblock istio upgrade and
development.

Tracking issue for istio upgrade [3]
