Add support for migrating timeouts from RabbitMQ #777
Description
Describe the feature.
Describe the requested feature
The timeout migration tool currently only lets you specify a persistence as a source. When users are looking to migrate from one transport to another, or even from one broker instance to another, there is no tooling to assist them in migrating delayed messages. This is particularly problematic for RabbitMQ since it has a proprietary implementation of delayed delivery.
The new feature would allow you to specify a RabbitMQ instance as a source for delayed message migration.
Describe alternatives you've considered
None. Due to the proprietary nature of the implementation on RabbitMQ, it is not reasonable for users to develop their own custom migration scripts.
