enhancement: do not enable all roles by default.

from now on, not all unified roles are enabled by default, instead the available roles are hand-picked in the default setup.

For advanced use-cases, the administrator is capable to enable the desired set of available roles.

Picking roles is not easy since the uid is NOT humanly readable, therefore a cli is contained which lists the available, disabled and enabled roles.
