ClickHouse Keeper now reports its running availability zone via the /keeper/availability-zone path.

Why it matters

This feature allows users to determine the availability zone where a ClickHouse Keeper instance is running, which helps in managing distributed deployments and improving fault tolerance by enabling awareness of the instance's geographical location.

How to use it

Configure the availability zone by setting the <availability_zone> value in the Keeper configuration file, for example:

<availability_zone>
us-west-1a
</availability_zone>


The availability zone can then be queried from the /keeper/availability-zone path.
