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

The RabbitMQ microservice client allows only the property relative to socket options to the underlying ampqlib as per line client/client-rmq.ts:136. There is no way to pass additional connection options like ssl certificates and client certificates or to specify a different authentication method like EXTERNAL.

Describe the solution you'd like

Add a key to RmqOptions or substitue RmqOptions#socketOptions with the full options object

Teachability, documentation, adoption, migration strategy

External Authentication method: Here
amqplib ssl example passing certificates to the connect handler: Here
amqplib ssl EXTERNAL auth example: Here
ampqlib EXTERNAL auth method issue: Here

What is the motivation / use case for changing the behavior?

Impossibility of integrating RabbitMQ inside an existing microservice architecture because RabbitMQ is configured with mTLS authentication.
