      Description

      In the current placement policy there all rules generate a queue name under the root. The only exception is the nestedUserQueue rule. This rule allows a queue to be created under a parent queue defined by a second rule.

      Instead of creating new rules to also allow nested groups, secondary groups or nested queues for new rules that we think of we should generalise this by allowing a parent attribute to be specified in each rule like the create flag.

      The optional parent attribute for a rule should allow the following values:

      • empty (which is the same as not specifying the attribute)
      • a rule
      • a fixed value (with or without the root prefix)
