Test for floating ip ranges
Expected ips arrays should have single dimension
Bug: wrong assignment. Networks has networks property
Nodes were not assigned to roles
Wrong nodes variable was put into get_nailgun_node_roles function
Change input paramater of assert_cluster_floating_list function. Ip -> node_name
Update params of update_network function
look for floating networks before assigning ip ranges
Change assertation in assert_cluster_floating_list function
All function accepts iterable value
