utils/fetch_os_creds.sh: Fuel: Robust creds fetch

In case ctl01 node is down, the current mechanism will return
invalid data (the string "Minion") instead of a valid controller IP.

Since "keystonercv3" is present on all controller nodes at </root>,
adjust the credentials fetch to use the first online controller node.
