[9.1][updates] pkg_upgrade task doesn't start on nodes with plugins

[Ruslan Khozinov]

Detailed bug description:

Fuel has been updated successfully.
Env update has been finished with successful result.

When I've checked the deployment history for the latest deploy
I've not found that pkg_upgrade task has been started for the node with kibana-grafana role
But for contoller+murano and cinder+compute nodes the pkg_upgrade task has been started.

Steps to reproduce:

1. Deploy Fuel9.0
2. Install stacklight and murano plugins from the mirantis catalog
3. Deploy an env:
  - contoller+murano_node
  - compute+cinder
  - kibana+grafana
4. Update fuel and the env up to Fuel 9.1

I've checked dpkg.log from controller (http://paste.ubuntu.com/23828140/)
