Enhanced autoscale clusters for FortiGate VM

This improvement supports the visibility of autoscale VM clusters on FortiManager, and its ability to read cluster information from new secondary members.

When a FortiGate VM secondary is added to a cluster, the new secondary member can query the cluster about its autoscale environment. FortiManager can then run this query on the new secondary member to update its autoscale record.

To view cluster information from a secondary member:

# diagnose sys ha checksum autoscale-cluster

Cluster information sample

Sample cloud topology:

FGT_BYOL; primary; 10.0.0.6; FGVM04TM00000066

FGT_BYOL; secondary; 10.0.0.7; FGVM00000000056

FGT_PAYG; secondary; 10.0.0.4; FGTAZ000000000CD

FGT_PAYG; secondary; 10.0.0.5; FGTAZ0000000003D

From the secondary, you can see cluster checksums and the primary device.
