Index auto-failover

When an index service is co-located with a data service, the auto failover of the node will be determined solely by the data service. In other words, the data service has priority, and the status of the co-located indexing service will not be taken into consideration.

When an index service is not co-located with a data service, ns-server will auto fail over the node using the current Node Availability auto-failover settings.

Documentation -

1. The time setting for auto failover, in the case of data service support for fast failover (i.e. 5s), can lead to false to failover if this is set to a small value.
2. Data service auto failover can cause loss of index, with the colocation use cas and when the index does not have a replica - This could happen before 7.1.
