ANN RabbitMQ PerfTest 2.8.0 GA is released

[Arnaud Cogoluègnes]

On behalf of the RabbitMQ team I'm happy to announce that RabbitMQ
PerfTest tool 2.8.0 GA is available. This is a maintenance release
with new features and dependency upgrades. With this release, PerfTest
can now simulate more dynamic workloads: variation of message size and
publishing rate, optional polling consumers (instead of asynchronous
consumers by default), optionally nack messages instead of acking
them. See the changelog [1] for more details. All users are encouraged
to upgrade to this version.

Changes:
* Bump dependencies (RabbitMQ Java client, Micrometer, Jetty)
* Add option to re-connect to RabbitMQ on PerfTest startup
* Add option to vary publishing rate
* Add option to consume messages via basic.get
* Add option to vary message size
* Add option to nack messages
* Make sequence of actions in consumer more logical
* Consumer rate limitation is broken if rate varies
