make timeouts configure from task or conf file and not hard-coded

[Asaf Hirshberg]

while running some tests i had to modify the code in order to play with time-outs of wait_for_ping:

    def _wait_for_ping(self, server_ip):
              bench_utils.wait_for(
                 server_ip,
                 is_ready=self._ping_ip_address,
                 timeout=300

parameters like that should be modify in the JSON/YAML or some centralized location instead of modifying code or a default value in the code and an option to change it in the JSON/YAML.

I believe it should be at least in rally.conf
