The batch-jberet subsystem fails when a remove operation is invoked.

[standalone@localhost:9990 /] /subsystem=batch-jberet:remove
{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0171: Removing services has lead to unsatisfied dependencies:
Service org.wildfly.batch.thread.pool.batch was depended upon by service org.wildfly.batch.configuration",
    "rolled-back" => true,
    "response-headers" => undefined
}

The batch configuration dependency needs to be removed before the its dependencies are removed.

The thread-pool resource should also require a reload before removal. The thread-pool is used in deployments and therefore shouldn't just be removed without a reload if there are deployments using it.
