Hello! I have a proposal for new rolling restart: filter by datacenter option.

By now, we do not have such option and, if we want to have datacenter-by-datacenter update, we have to use "hosts-filter" option, where we set this hosts in advance(and pray that this list is constant and never changes)

Option "dc-filter"(or some more pleasant name) will allow to restart hosts in any provided DC, comma-separated

For example, rolling --dc-filter=MAN,SAS

Or something like that

Looks like this could be taken from Ydb_Discovery.NodeLocation in Ydb_Maintenance.Node. I will need to investigate whether this struct can be empty for some reason (just the gut feeling that it can...).

--dc-filter not implemented yet, moved it to a separate issue in ydbops repository: https://github.com/ydb-platform/ydbops/issues/5
