yardstick env influxdb/grafana cmd support centos

JIRA: YARDSTICK-714

Currently yardstick env influxdb/grafana command do not support centos.
Because we use the gateway ip to get the service of influxdb and grafana.
But in centos, we can not access influxdb/grafana service via gateway ip.
In this patch, I use docker inspect to get the ip of influxdb and grafana.
So these command can support centos.
