Group and Policies settings

[qianwei-yin]

The entry of the permission settings can be found in the hamburger button (main nav).

These are the main views of permission settings:

1. table view: display group and policy data.
   • viewed by group: to see what users are in a group
   • viewed by user: to see what groups a user has
   • policy table: display the policy's entity object, target object and permission
2. group detail view: allows bulk editing members in this group
3. user detail view: allows bulk editing groups of this user
4. new group view: create a new group
5. permission calculator view: to know what is the effective permission on a target (bc some policies have priorities over others, some polices can be OR'd with some others).
6. permission edit/create view

Note: "Policy" in UI means "RowProtection" in the backend.
Note: "Delete policy feature" is not done bc it has a bug in the backend, will create another PR.
