Support for configuring BGP sessions for "Virtual Machines"

[m-rhode]

Hello,

first of all thanks for writing this plugin!

Is your feature request related to a problem? Please describe.
I'd like to configure a BGP session between a netbox device and a netbox virtual machine (both sides configured in netbox)

Describe the solution you'd like
Be able to select a Virtual Machine for a BGP session, currently only "devices -> devices" and not "virtualization -> virtual machines" can be selected.

Describe alternatives you've considered
to not configure the BGP session for the VMs via netbox BGP plugin 🤷

Thanks for considering this
