Create permissions and menu items if none previously existed

The `infrahub db update-core-schema` command will now also create menu
items and permission objects assuming that no previous menu item exists
for the new menu, and the same for permissions if one permission has
been defined this step will be ignored otherwise full permissions will
be assigned to the existing users and the Infrahub Users group will be
created.

This is a bit of a poor mans migration as these type of objects don't
fit into the typical current workflow.

```bash
infrahub db migrate
infrahub db update-core-schema
```
