[validation tool] should give more feedback

[Eugene Korekin]

Mirantis validation tool gives too little feedback if there is not enough nodes to deploy cluster.
It just waits for nodes to become available.

I propose to give some feedback in that case.

Actually the root cause of the issue is the following infinity cycle in the function match_nodes() file main.py

========== start quotation ==============
def match_nodes(conn, min_nodes, probe_cnt):

    while True:
        nodes = [node for node in fuel_rest_api.get_all_nodes(conn)
                 if node.cluster is None]

        if len(nodes) < min_nodes:
            templ = "Only {0} nodes available. {1} requires. Wait 60 sec"
            logger.info(templ.format(len(nodes), min_nodes))
            time.sleep(60)
            continue
=========== end quotation =============

Actually the logger save message on the info level, but due to the all logging is miss-configured, there is no logs at all
