* after having decided that the Groupware API should be a standalone
independent custom REST API that is using JMAP data models as much as
possible,
* removed Groupware APIs from the Graph service
* moved Groupware implementation to the Groupware service, and
refactored a few things accordingly
We agreed to move the 'opencloud_full' example to a new directory to
avoid confusion with the supported compose examples in
opencloud-compose.
This commit keeps the bare-metal example in place as that is still
mentioned in the documentation.
