Feature request for OR match option for multiple constraints when creating a service

[n0nvme]

Description
At this moment there is no way to create service constraints with OR match pattern
For example: node.datacenter==DC1 OR node.datacenter==DC3

Of course, you can exclude all other labels, but you will need to update all services constraints when labels are changed

Is it possible to add support for this use case? The new rule may look like node.datacenter|=["DC1", "DC3"]
