Mikhail Efremov updated IGNITE-26459:
-------------------------------------
Description:
*Description*
The main goal is to create a new POST method in REST API module (follow the
[guidance|https://github.com/apache/ignite-3/blob/main/modules/rest/README.md]).
The current approved URI is
{{/management/v1/cluster/zone/datanodes/recalculate}} and the method should
accept a list of zone names to recalculate data nodes for. The controller
should use new public method for data nodes recalculation from IGNITE-26543.
The corresponding REST API tests should be provided.
*Motivation*
In case of scaleUp/Down disabled the only way to adjust dataNodes and thus
recalculate assignments is to alter zone filter. Despite the fact that it works
we need a more user-friendly way to do this. Meaning that we need new CLI
command within 'distribution' group. We already implemented
*Definition of done*
# Possibly new controller for {{zone/datanodes}} commands is created.
# New POST method with the list of zone names as the argument to call.
# REST API tests for the new method.
or overloading already existing 'reset'.
DZM internal changes should be pretty trivial - effectively it's the same as
altering filter, but we need to keep compatibility aspects in mind.

recalculate assignments is to alter zone filter. Despite the fact that it works
we need a more user-friendly way to do this. Meaning that we need new CLI
command within 'distribution' group. We may consider either adding a brand new
command or overloading already existing 'reset'.

altering filter, but we need to keep compatibility aspects in mind.
