Change IP parsing to not depend on spaces in names

Prior method of extracting the controller IP was relying on the fact
that default node names have spaces in them and hence generate 9 fields
before the IP address.
This change proposes to change awk tokenizing to divide string by
column separator in `fuel node` output.
