About storage for GroupState

[streetycat]

In the development process of "Group", I need an storage module based on the CYFS kernel. I have several requirements:

1. It can store the kernel information of the "Group" module, including APP status information and consensus chain information. The specific content is described in:
   https://github.com/buckyos/CYFS/issues/71#issuecomment-1378616109

2. Similar to RootState, the objects mounted on it will not be recycled

3. Authority:

• Can be modified by the "administrator" of the "group", but cannot be modified by the ordinary "member",

• Can be read by the "members" of the "Group" (either in the same OOD or not) and synchronized to the corresponding location on the respective RootState

• Other members and "DEC" access the corresponding state through the "Member" RootState of "Group", with the same permissions as the RootState

At present, there is only one global-state of cyfs-stack, which is the state of the current protocol stack identity (People object usually), which is divided into root-state and local-cache
From the perspective of group requirements, a parallel group-global-state should be added, which belongs to the corresponding group identity; considering that cyfs-stack may support multiple identities in the future, that is, each identity will have a corresponding global-state

[lurenpluto]

Regarding the permissions control of group-state, group-state should only be a component and a set of internal interfaces provided by cyfs-stack, and will not directly provide RPC layer interfaces for external access; group components provide externally accessible RPC interfaces, And can directly access all group-states, so permission control should be implemented inside the group component for better

Thank you, Is there someone can help me to support it. maybe it'll update the core code existed.
