Unavailable regions should not show in --region completion values in kafka create

[craicoverflow]

Description

Version: 0.39.0

The user that I am logged in as can either create eval Kafka instances or standard ones. Not all regions are available for all instance types. In interactive mode unavailable regions are filtered out, but these still show up for completions.

Steps to reproduce

Run rhoas kafka create and select eu-west as your region, which is invalid. We should not show this as a valid value.

$ rhoas kafka create --provider aws --region
eu-west-1  us-east-1

Solution

The same function should be used in both scenarios to ensure data consistency.

I have implemented that but needed to temporary disable this
