[Kafka] Ability to set a prefix for Transactional ID

[brunodomenici]

Is your feature request related to a problem? Please describe.

Today we need to give permissions for managing transactions in Kafka with the pod name of the sensor, which could lead to collisions in a mutualized Kafka environments.
Image 2 different teams working in separated namespaces with the same sensor name using the same Kafka instances with different Kafka credentials. We need to give:

User:user1,TransactionalId,PREFIXED,pod-name-,Write,Allow,*
User:user2,TransactionalId,PREFIXED,pod-name-,Write,Allow,*

I know the pod name will have the suffix of the ReplicaSet hash, but in the Kafka side we have 2 users who can potentially manage the same transaction id.

Describe the solution you'd like

Ability to configure a prefix for this, like commented in #2654 (comment) would fix the issue.

Describe alternatives you've considered

Give the same Kafka permissions for all users.

Additional context

This is the same of #2654 but it's closed, so I decided to create a new one.
