[UX2.0] configuration_group not handling encrypted variables properly

[tzarski0]

When you configure any configuration group with encrypted filed as variable (e.g. aaa user password_variable). The first time you push the TF apply, it works. Right after when you do TF apply again, you see a diff although you didn't change anything:

  ~ resource "sdwan_configuration_group" "configuration_group" {
      ~ devices               = [
          ~ {
                id        = "C8K-3D1A8960-6E76-532C-DA93-50626FC5797E"
              ~ variables = [
                  - {
                      - name = "failsafe_password" -> null
                    },
                  + {
                      + name  = "failsafe_password"
                      + value = "cisco123"
                    },

It seems like when we GET variables from Manager, the Manager returns just name without value for encrypted field and this causes change in configuration. We should find a way to handle passwords without always showing diff if password didn't change.
