Strps to reproduce:
1. Install Fuel Master.
2. Deploy env with Sahara in HA mode.
3. Add sahara image and add sahara image tags.
4. Run Sahara platform tets.
5. Check to pass test.
6. Shutdown primary controller node.
7. Run Sahara platform tets.
Expected result: test is passed.
Actual result: test is failed.

to resolve:
change ssh method in line:

(Test is failed because ssh method tried to open ssh channel to offline node)

    Fix for SSH method of OSTF tests

    In SSH method of OSTF tests address of controller node is chosen
    as the first from list of controller nodes.
    It may not work when we have a few controller nodes (HA mode) and one
    of controller nodes went away. Now controller node is chosen
    from list of controller nodes online.
