List Grants API

[shaiktas]

Hello Team,
Do we have any API to list down the privileges attached to a given role. Currently when we try to drop a role,
API milvusClient.dropRole(DropRoleParam.newBuilder().withRoleName("xxx")), complaining with below error :
reason: fail to drop the role that it has privileges. Use REVOKE API to revoke privileges. Also from attu when we trying to delete Role by clicking on Role, Select role, delete button it is navigating back to login page.

you will need to revoke all the priviledge of a role before drop a role.
I believe there should be a describeRole API

client.describe_role(role_name="role_a")

then, you can remove all the priviledge by revoke_privilege_v2
