(Future) support php-amqplib/php-amqplib 3.0 #1145
Description
Current php-amqplib/php-amqplib version 2.x is in fact incompatible with PHP 8, and they actually specifically prohibit installing it on PHP8 since 2.12.2. However, a new version, v3.0.0, is soon planned for release, and the release candidate already exists.
However, enqueue/amqp-lib does only allow installing version ^2.10, so it is not compatible with the upcoming version.
This means we in fact cannot use this transport in combination with PHP 8, so this issue relates to #1108
