This commit adds auto-configuration for the generic AMQP 1.0 client
in Spring AMQP 4.1, using Qpid ProtonJ. Support for connection factory,
client and listener endpoints are available.
The "spring.amqp" namespace exposes settings to connect to an AMQP 1.0
compliant broker and customize client and listeners settings. Docker
compose and testcontainers support using RabbitMQ, ActiveMQ, and Artemis
have been added too.
Closes gh-49678
Now that Spring AMQP supports AMQP 1.0 as well, we need to straighten
out our existing support. AMQP 0.9 is RabbitMQ specific, so we can no
longer refer it to "amqp". This commit migrates the existing support
to spring-boot-rabbitmq and renames the starters as well.
For continuity, users should migrate from "spring-boot-starter-amqp"
to "spring-boot-starter-rabbitmq". While the root package has been
changed for consistency, most names are the same, including
configuration properties still in the "spring.rabbitmq" namespace.
Keys to configure the version of the RabbitMQ clients have migrated to
'rabbitmq.client' and 'rabbitmq.stream.client' respectively.
Closes gh-49677
