[BUG] Regression on TLS auth to Crowdsec

[mathieuHa]

Describe the bug 🐛
Version 1.1.13 of the plugin could use TLS auth for the bouncer to the LAPI using the exemple tls-auth.
Version 1.3.0 returns an error validating the certificate of the LAPI

traefik  | DEBUG: CrowdsecBouncerTraefikPlugin: 2024/05/01 17:06:27 ServeHTTP:handleNoStreamCache ip:172.22.0.1 isBanned:t crowdsecQuery url:https://crowdsec:8080/v1/decisions?ip=172.22.0.1&banned=true Get "https://crowdsec:8080/v1/decisions?ip=172.22.0.1&banned=true": tls: failed to verify certificate: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "CrowdSec Test CA Intermediate")

Expected behavior 👀
Plugin is still able to validate LAPI certificate

Context 🔎

Version (please complete the following information):

• OS: [All]
• Traefik version: [ 3.0.0]
• Plugin version: [>1.1.13-1.3.0]

To Reproduce

make run_tls
docker compose -f examples/tls-auth/docker-compose.yml exec -it crowdsec bash
cscli bouncer list

Expected result:

It was due to a "race".
Traefik only load plugin configuration on startup, and the certificate is generated at that time.
If certificate is changed after Traefik is started, another restart is necessary.
