Thinking about providing more granularity on authorization (ie, grant
access to a normal user to create a VM on Kimchi, for example) the user
role (sysadmin or normal user) was linked to the UI tabs instead
of the API itself
It can cause multiple issues, for example:
- different plugins with the same tab name (the case of Ginger and
Kimchi) will get the authorization settings merged
- what about an API in use for different tabs?
To avoid those problems, remove the role_key parameter and also do not
link UI tabs with user role.
