    Task: add HostAPI method sync_resources
    
    This method provides new functionality to the python tasks. With this
    the user can specify exactly which resources should be synchronized to
    a single slave machine.
    
    Since in case of python tasks all resources are automatically
    synchronized this method doesn't have any practical meaning yet. This
    will be changed in the following commits.
    
    Example of use:
    
    m1 = ctl.get_host("1")
    m1.sync_resources(modules=["IcmpPing"], tools=["multicast"])
