Add a link to the parent Prefix in IP Ranges

[a-belhadj]

NetBox version

v.3.3.6

Feature type

Change to existing functionality

Proposed functionality

I want to see the parent prefix of an IP range when I look at my IP range (https://mynetbox/ipam/ip-ranges/2/)
A simple way to implement that is to display the prefix of a random IP in the range, but it will not work if the range goes through multiple prefixes.

Use case

We want to move our "fake" prefixes to IP ranges, but it's hard to know the parent prefix of an IP Address.

Database changes

It should be a computed value and shouldn't change the database

External dependencies

No dependencies

This is implemented in #10692.

Marking this as blocked by #7845. We need to determine an efficient way of automatically mapping child IP addresses, ranges, and prefixes to their parent prefixes.

Absent a solution for #7845, we can just do what we do for IP prefixes currently: Dynamically resolve any containing prefixes and list them in a table on the page.
