Add SNMP V3 support for events/traps in HMC

Hello, we are implementing monitoring of SNMP events in WWAO focal point and seems it's possible to setup trap in HMC (8561-T01 z15) using V1 only but customer would like to have V3 due to security reasons.

    The HMC currently supports SNMP V3 for requests and responses and while it would be possible to use V3 for SNMP traps as well it is not likely this is the direction that will be taken. Moving forward it is important to make sure any encryption used by the HMC is quantum safe (not all existing encryption algorithms are quantum safe). The currently supported SNMP V3 encryption support is not quantum safe. With this in mind the direction for encryption support for SNMP traps will likely move in the direction of using TLS, which lends itself to quantum safety more easily.

    Depending on the SNMP traps desired, it might also be possible to get the same information via the HMC web service APIs and/or remote syslog support provided by the current level of HMC. The notification support of the HMC web service APIs flows over a TLS encrypted connection. The remote syslog support can be used to flow certain events over TLS encrypted connections from the HMC to customer provided syslog servers. Both of these provide another way of getting some of the same events over encrypted paths.

    WWAO is based on IBM Netview (which process SNMP events) - it does support some TLS but not it's not clear whether it's available for our purposes or how to use that for SNMP receiver (task CNMTRAP)

    Please provide more information on WWAO focal point and if it supports TLS connectivity
