ServiceBusRules must belong to Rules

Hello Azure colleagues!

I found an issue in the: specification/servicebus/resource-manager/Microsoft.ServiceBus/stable/2017-04-01/Rules.json

It must belong to Rules and not Subscriptions

As OpenApiGenerator is using the tags to group the APIs it will result in putting this unique method in the SubscriptionApi instead of the RuleApi.

Here is an example of fix:
https://github.com/speedfl/azure-rest-api-specs/pull/1/files

However I don't have the vision of the impact. I let you see.

Have a good day

Start with specification/servicebus/resource-manager/Microsoft.ServiceBus/stable/2017-04-01/Rules.json and inspect the ServiceBusRules tags and parent resource relationship. Compare the proposed change in the linked example, then verify that OpenApiGenerator groups the method under RuleApi rather than SubscriptionApi and check for any affected generated API groupings.
