Support Multiple Panorama Endpoints

[jdrew82]

Environment

• Nautobot version: 1.4.3
• nautobot-chatops version: 1.3.1
• nautobot-plugin-chatops-panorama version: 1.1.0

Proposed Functionality

For larger enterprise customers it's not unusual to have multiple instances that they manage firewalls. This can be due to the separation of duties, wanting to manage differing environments or limitations on resources. It'd be helpful to be able to query multiple Panorama endpoints depending upon the environment or device I want to query.

Use Case

For enterprise environments that manage multiple Panorama instances for differing environments or separation of duties.

In Nautobot Chatops, this is going to be implemented as a new model, likely to be coming from another App. Please see #122.
