Ability to expose additional ports

[rrileyca]

Is your feature request related to a problem? Please describe.
RabbitMQ has added a new plugin (RabbitMQ Streams) which can be enabled with:

embedded.rabbitmq.enabled-plugins[0]=rabbitmq_stream

Unfortunately, the container does not expose this port as configured.

Describe the solution you'd like
The RabbitMQ stream port of TCP 5552 open. Alternatively, an ability to add additional Docker ports as a generic capability.

Describe alternatives you've considered
This might be a duplicate: #755

Additional context
It would perhaps be easier to add RabbitMQ Streams support in the embedded-rabbitmq module instead.
