MQOPEN option for queue manager quiescing

If we use the MQOPEN call when the queue manager is in a quiescing state, the call might fail, depending on which environment we are using.

In the CICS environment on z/OS, if we use the MQOPEN call when the queue manager is in a quiescing state, the call always fails.

In other z/OS environments, IBM i, Windows systems and in UNIX and Linux systems environments, the call fails when the queue manager is quiescing only if we use the MQOO_FAIL_IF_QUIESCING option of the MQOPEN call.
