> When using subscribe with a java regex (Pattern), we need to resolve it on 
> the client side to send the broker a list of topic names to subscribe to.
> Context:
> The new consumer group protocol uses [Google 
> RE2/J|https://github.com/google/re2j] for regular expressions and introduces 
> new methods in the consumer API to subscribe using a `SubscribePattern`. The 
> subscribe using a java `Pattern` will be still supported for a while but 
> eventually removed.
>  * When the subscribe with SubscriptionPattern is used, the client should 
> just send the regex to the broker and it will be resolved on the server side.
>  * In the case of the subscribe with Pattern, the regex should be resolved on 
> the client side.
> As part of this task, we should re-enable all integration tests defined in 
> the PlainTextAsyncConsumer that relate to subscription with pattern and that 
> are currently disabled for the new consumer + new protocol
