MOS 9.1 -> 9.2 (MOS_UBUNTU_MIRROR_ID=9.0-2017-01-22-152420)
Contrail version 5.0.0 -> 5.0.1

Steps to reproduce:
1. Deploy environment mos fuel 9.1 with contrail plugin
2. Update contrail plugin from 5.0.0 to 5.0.1
3. Update environment to 9.2
Install mos-release package (Change proposed yum repository if you don't wan't to use lates repo)
yum install -y http://mirror.fuel-infra.org/mos-repos/centos/mos9.0-centos7/snapshots/proposed-2017-01-21-204421/x86_64/Packages/mos-release-9.2-1.el7.x86_64.rpm

Install mos-playbooks package.
yum install -y mos-playbooks

Update the Fuel Master node:
ansible-playbook playbooks/mos9_prepare_fuel.yml
ansible-playbook playbooks/update_fuel.yml -e '{"rebuild_bootstrap":false, "snapshot_repo":"snapshots/<MOS_UBUNTU_MIRROR_ID>", "snapshot_suite":"mos9.0-proposed"}'
ansible-playbook playbooks/mos9_fuel_upgrade_kernel_4.4.yml

Update an existing Mirantis OpenStack environment:
ansible-playbook playbooks/mos9_prepare_env.yml -e '{"env_id":<ENV_ID>, "snapshot_repo":"snapshots/<MOS_UBUNTU_MIRROR_ID>", "snapshot_suite":"mos9.0-proposed"}'

Update the environment:
fuel2 update --env <ENV_ID> install --repos mos9.2-updates

Upgrade the Ubuntu kernel to version 4.4:
ansible-playbook playbooks/mos9_env_upgrade_kernel_4.4.yml -e '{"env_id":<ENV_ID>}'

Actual result:
Contrail `s packets have been removed from compute node
