Keep the current traffic manager name

When running under kitchen/vagrant:

This traffic manager is currently called 'default-ubuntu-1204.vagrantup.com' which resolves
to '127.0.1.1', not found in the raised IP addresses: '10.0.2.15'.
Would you like to

1. Keep the current traffic manager name (default)
2. Specify a new resolvable hostname
3. Use an IP address instead of a hostname
