Debug why no default user in Ansible ODL

ODL is designed to have a default admin user. The packaging project ensures that the user is present. The script dedicated for this task is:

https://git.opendaylight.org/gerrit/gitweb?p=releng/builder.git;a=blob;f=jjb/packaging/test-rest-ok.sh

The absence of this user in Ansible-ODL is confirmed by the test logs, which checks the initial state of the users.
