LibreNMS Force Add and Poller Support

[bile0026]

Environment

• Nautobot version: 2.3.16
• nautobot-ssot version: 3.4.0

Proposed Functionality

Add SNMP credential support to allow the force_add parameter to work correctly.

Add Poller Group support to assign devices to a specific poller/group within LibreNMS as they are added from Nautobot.

These will likely need to be accomplished using Config Contexts as snmp versions and credentials can vary by device and device type. Need flexibility to allow snmp v1,v2c, andv3 and various snmpv3 options like auth/priv parameters.

Use Case

Devices might be slow to respond or not accessible by the main LibreNMS server which causes the normal add with SNMP discovery to fail. This is also required to add a device directly to a remote/distributed poller since the ICMP check is run from the main LibreNMS server.
