NETOBSERV-1869 PoC on UDN UI

[jpinsonneau]

Description

This is a PoC around UDN improvements in netobserv UI using mock data.

You can run this UI locally using:

$ make start-standalone-mock

Implementations:

• UDN graphs
• extra column + filter on UDN name
• topology grouping
• clickable links bringing to UDN definition (need namespace field)
• topology nodes / edges colors per UDN
• additionnal 'Network traffic' tab for UDN kind

We need to decide how to store the UDN info. These can be namespaced so it will be good to have both Name + Namespace in two separate fields as we did for other K8S enrichments.
Or maybe we could reuse SrcK8S_Namespace ?
