Hubble Not Working With Cilium v1.12.1

[LukasNajman]

Hubble stopped working after #9225, which upgraded Cilio to v1.12.1. As part of PR, Hubble deployment was not modified and is now incompatible with Cilio v1.12.1.

When deployed with the following settings

### Enable Hubble without install
cilium_enable_hubble: true
### Enable Hubble Metrics
cilium_enable_hubble_metrics: true
### if cilium_enable_hubble_metrics: true
cilium_hubble_metrics:
 - dns
 - drop
 - tcp
 - flow
 - icmp
 - http
### Enable Hubble install
cilium_hubble_install: true
### Enable auto generate certs if cilium_hubble_install: true
cilium_hubble_tls_generate: true

hubble-ui pod ends up in CrashLoopBackOff as proxy container (envoy) fails to start. When I looked at the newer version of Hubble deployment, I can see that envoy was replaced by nginx.

Environment:

• Azure
• Ubuntu 22.04
• Ansible 2.12.5
• Python 3.8.10

Kubespray version (commit) (git rev-parse --short HEAD):
5a978d78

Network plugin used:
Cilium v1.12.1
