Add support for messageId, correlationId, and type in RabbitMQ bindings

[abossard]

Description

This pull request introduces several enhancements to the RabbitMQ bindings and metadata utilities. The most important changes involve adding new utility functions to extract specific metadata fields and updating the RabbitMQ publishing functions to utilize these new utilities.

Enhancements to metadata utilities:

• metadata/utils.go: Added TryGetMessageId, TryGetCorrelationId, and TryGetType functions to extract messageId, correlationId, and type from metadata properties, respectively. [1] [2]

Updates to RabbitMQ bindings:

• bindings/rabbitmq/rabbitmq.go: Modified the Invoke method to extract and set MessageId, CorrelationId, and Type from the request metadata using the new utility functions.
• pubsub/rabbitmq/rabbitmq.go: Updated the publishSync method to extract and set ContentType, MessageId, CorrelationId, and Type from the request metadata using the new utility functions.

Please run our linter. make lint and fix lint issues.

As discussed, please do not add component specific code to metadata/utils.go - this should go into common/component/rabbitmq

Also you need to add tests:

Unit tests for Rabbit MQ Binding:

• https://github.com/dapr/components-contrib/blob/main/bindings/rabbitmq/rabbitmq_test.go

Unit tests for Rabbit MQ Pubsub:

• https://github.com/dapr/components-contrib/blob/main/pubsub/rabbitmq/rabbitmq_test.go

Integration test (if applicable):

• https://github.com/dapr/components-contrib/blob/main/bindings/rabbitmq/rabbitmq_integration_test.go

Certification Tests (required for stable components in Dapr):

The Rabbit MQ Bindings certification test should be updated to add a test case that exercises these new options:

• https://github.com/dapr/components-contrib/tree/main/tests/certification/bindings/rabbitmq

The Rabbit MQ PubSub certification test should be updated to add a test case that exercises these new options:

• https://github.com/dapr/components-contrib/tree/main/tests/certification/pubsub/rabbitmq

To run the certification tests go into those repos and simply run go test -v --count=1 . -- if you run into an error complaining about protos you need to first run export GOLANG_PROTOBUF_REGISTRATION_CONFLICT=ignore

This is not the right place for your RabbitMQ component specific shared code.

Instead of metadata/utils.go, create a rabbitmq folder here: https://github.com/dapr/components-contrib/tree/main/common/component

Then import from there. Please add a unit test for these helper methods.
