    Openstack configuration can not be updated in not ready nodes

    Add check that configuration update can not be executed if
    any of target nodes are not in 'ready' state.

    Current solution is:

    - If any deployment is running, then uploading new
    configurations, deleting old ones and execution updates are prohibited
    in order to keep cluster configuration in a consistent state

    - By default Execute update can be done successfully, only if
    cluster is in state 'operational' and *all* target nodes to update
    are in the state 'ready'.

    - 'force' flag allows to execute update configuration only on target
    nodes which is currently in state 'ready'. Other target nodes will be
    ignored. We assume that, these nodes nodes will get an updated
    configuration during deployment.
