Take effect without restart by updating some clickhouse configuration

[xzy256]

Clickhouse support some configuration take effect without restart, such as keep_alive_timeout 、max_thread_pool_size 、max_connections etc. But when i use operator, no matter config

configuration:
    files:
      config.d/xxx.xml

or

configuration:
    files:
      conf.d/xxx.xml

or

configuration:
    settings:
        key: value

When apply yaml by kubectl, the pods restart after some seconds. Does operator support the function or not ?

We plan to add a special syntax to specify if clickhouse needs to be restarted for a particular setting change or not.

@alex-zaitsev is this flag to force clickhouse to restart has been implemented? I'm trying to find a more elegant way to re-apply some changes rather than kubectl delete -f ... && kubectl apply -f ...

Thanks
