Allow Probe Scheme to Be Customized

[Kyle-Cooley]

Addresses #2513. This change allows the scheme used for the liveness and readiness probes to be overridden to HTTPS when needed. The approach taken was minimalistic.

Verified using this groovy script saved to /tmp/helloworld.groovy

from('timer:tick?period=3000')
  .setBody().constant('Hello world from Camel K')
  .to('log:info')

and an integration deployed with the following commands

openssl req -x509 -newkey rsa:4096 -keyout /tmp/integration-key.pem -out /tmp/integration-cert.pem -days 365 -nodes

kubectl create secret tls my-tls-secret --cert=/tmp/integration-cert.pem --key=/tmp/integration-key.pem

kamel run \
  --property quarkus.http.ssl.certificate.file=/etc/camel/conf.d/_secrets/my-tls-secret/tls.crt \
  --property quarkus.http.ssl.certificate.key-file=/etc/camel/conf.d/_secrets/my-tls-secret/tls.key \
  --config secret:my-tls-secret \
  /tmp/helloworld.groovy \
  --trait container.port=8443 \
  --trait container.probes-enabled=true \
  --trait container.liveness-scheme=HTTPS \
  --trait container.readiness-scheme=HTTPS

Release Note

Allow the scheme used for the liveness and readiness probes to be overridden

Nice, thanks!

@Kyle-Cooley do you think you can include that simple example under trait/container example directory (it has to be created)?

[astefanutti]

Could you please run make generate-doc to reflect the changes into the documentation?

[Kyle-Cooley]

I've made those changes. Let me know if there is anything else.

[squakez]

Excellent, thanks a lot!
