Add superuser role to banderson user (#3)

User banderson is used in the shibboleth authentication demo. For that,
he needs to have a role in midPoint to be able to access the midPoint
GUI. Superuser role was chosen because the shibboleth authentication
replaces the internal authentication with default administrator account.
