    Improve partitions and disk metadata handling

    Partitions schema and disk metadata at nodes must be updated only
    if they are scheduled for reprovisioning, and the provisioning
    method has changed to incompatible (i.e. from 'cobbler' to 'image')
    due to the shift of release version.

    Move logic that manages partitions from upgrade handlers to function
    that actually initiates the re-provisioning of node. This ensures
    that for every node this is applied only once and only if necessary.
