    [QUEENS ONLY] Don't check openvswitch service if no ovs package.

    We only try to restart the ovs service if the package is present on
    the host.

    We also make sure that some tasks don't run on every step by providing
    the necessary conditionals.

    Queens only because:
     - master to stein ovs tasks are refactor to use an ansible module and
       we are careful to not error out when ovs isn't present.
     - rocky doesn't have the update tasks workaround for ovs.
