/**
* Add a role to a user
*
* This command allows for adding a specific role to an existing user.
*
* Roles can optionally be specified as a comma separated list. For all roles provided by Neos, the role
* namespace "TYPO3.Neos:" can be omitted.
*
* If an authentication provider was specified, the user will be determined by an account identified by "username"
* related to the given provider. However, once a user has been found, the new role will be added to <b>all</b>
* existing accounts related to that user, regardless of its authentication provider.
*
* @param string $username The username of the user
* @param string $role Role to be added to the user, for example "TYPO3.Neos:Administrator" or just "Administrator"
* @param string $authenticationProvider Name of the authentication provider to use. Example: "Typo3BackendProvider"
* @return void
