Reply-to queue aliases and clusters

A reply-to queue alias definition is used to specify alternative names for reply information. Reply-to queue alias definitions can be used with clusters just the same as in a distributed queuing environment.

For example:

An application at queue manager VENICE sends a message to queue manager PISA using the MQPUT call. The application provides the following reply-to queue information in the message descriptor:
```
ReplyToQ='QUEUE'
ReplyToQMgr=''
```
In order that replies sent to QUEUE can be received on OTHERQ at PISA, create a remote-queue definition on VENICE that is used as a reply-to queue alias. The alias is effective only on the system on which it was created.
```
DEFINE QREMOTE(QUEUE) RNAME(OTHERQ) RQMNAME(PISA)
```

RQMNAME and QREMOTE can specify the same names, even if RQMNAME is itself a cluster queue manager.
