Add host&targer in scenario['options']['server_name'] support

JIRA: YARDSTICK-810

Currently host, target is in scenario, but as a input, we prefer it in
scenario['options'].
So I add support for under scenario['options']['server_name']

If we write host in scenario['options']['server_name'], the host ip info
will be written in context.
