Get Recursive Nested AD Users in AAD Mode

[abuccts]

In current AAD mode, for the following two groups:

SG1
  SG1.User1
  SG1.User2
  SG2

SG2
  SG2.User1

If only SG1 is grant permissions, all users in SG2 won't have permissions.

Pending it.
Because the grouplist comes from Azure AD. And AD only give us the group which the user directly belongs to. Here we can't handle the issue recursively.
If we wanna get all user in a group which includes the user in the child group. We can change our logic to get user list from a group. Then recursively handle it.
