> From IGNITE-8571:
> Now we have only one way to change BLAT - manually update it via console.sh or API.
> We need to add the possibility to change it automatically. Adjust to current topology.
> So, I propose 3 new parameters which would be responsible to tune this feature.
>  1. Flag autoAdjustEnabled - true/false. Easy. Manual baseline control or auto adjusting baseline.
> 2. autoAdjustTimeout - time which we would wait after the actual topology change. But it would be reset if new discovery event happened. (node join/exit).
> 3. autoAdjustMaxTimeout - time which we would wait from the first dicovery event in the chain. If we achieved it than we would change BLAT right away (no matter were another node join/exit happened or not).
> We need to change API next way:
>  1. org.apache.ignite.IgniteCluster
> *Add*
>  isBaselineAutoAdjustEnabled()
>  setBaselineAutoAdjustEnabled(boolean enabled);
>  setBaselineAutoAdjustTimeout(long timeoutInMs);
>  setBaselineAutoAdjustMaxTimeout(long timeoutInMs);
> 2. org.apache.ignite.configuration.IgniteConfiguration
> *Add*
>  IgniteConfiguration setBaselineAutoAdjustEnabled(boolean enabled);
>  IgniteConfiguration setBaselineAutoAdjustTimeout(long timeoutInMs);
>  IgniteConfiguration setBaselineAutoAdjustMaxTimeout(long timeoutInMs);
> Also, we need to ensure that all nodes would have the same parameters.
>  And we should be able to survive coordinator left during parameters changes.
> -
>  For IGNITE-8575:
> Proposed API format for control.sh:
> {{--baseline autoadjust disable}}
> {{--baseline autoadjust enable <timeout>}}
