Create/manage queues within namespaces

Description

Currently, queues are identified by app + flow + flowlet.

Table names in Hbase:
cdap.system.queue.PurchaseHistory.PurchaseFlow

However, with namespaces, we could have the same app deployed in multiple namespaces, in which case this could be a problem.

The issue surfaced while adding namespaces to metrics, but this could be a much bigger problem.

Trying to investigate what it takes to add namespace to queues, but unsure at this point if this would be a risky fix for 2.7.0.

As part of this fix, we should also add the DELETE /v3/namespaces/<namespace-id>/queues API in AppFabric.

So we just need to prefix the table with the namespaceId if it is not "default"? Something like:

For default namespace, just keep the way it is now to be backward compatible.
