[FEATURE] UEs and gNB attached & Xnh targeting a gNB

[IgnacioCTO]

Hi, here I list some features that could be interesting to have:

• Have a way to check which users are attached to a certain gNB and vice versa.
• The possibility of targeting a specific gNB while performing a Xn or NG handover.
• The possibility of running an UE and a gNB in different VMs

Thank you for your work,

Ignacio
