In ticket #2920, amfd has rebooted the nodes that have duplicated 2N
assignments after split-brain. However, if there are spare 2N SUs hosted on
each payloads, amfd does not reboot the nodes that have duplicated assignments
and those assignments are remained intact after split-brain
Configuration:
- start cluster with 2 controllers + 6 payloads
- SC absence is enabled
- 6 SUs hosted on 6 payloads respectively, i.e SU1 hosted on PL3, SU2 on PL4,
...
- SU1 and SU2 initially are given 2N Active/Standby assignments
- Split network to separate PL3 and PL4 apart from cluster. Since SC absence is
enabled, PL3 and PL4 don't reboot
- Now SU3 (PL5) and SU4(PL6) are given 2N Active/Standby assignments
- Split network two partitions, [SC1, PL5, PL6] and [SC2, PL7, PL8]
- The second partition has SC2 becomes active, so the SUs in PL7 and PL8 are
given assignments.
- Restart SCs.
- After both SCs come back from reboot, there are totally 3 Active(s) and 3
Standby(s) assignments
Synced from headless

In avd_sg_2n_act_susi(), amfd always picks the first two assignments, which are
correctly active and standby, thus amfd didn't reboot the nodes
