SP & Gateway liveness and readiness should be customizable

[jeanmi151]

Here in the chart is not permitted to custom liveness and readiness probes

helm-charts/georchestra/templates/security-proxy/security-proxy-deployment.yaml

Line 68 in eddc8ea

livenessProbe:

gateway as well

helm-charts/georchestra/templates/gateway/gateway-deployment.yaml

Line 56 in eddc8ea

livenessProbe:

Ideally I would like to not allow customization but instead globalize all the liveness. This makes it easier to upgrade those parameters globally on all the clients.

We managed to do it like this, I think we can keep doing it this way.

Recent example I proposed pierre to modify the liveness globally: #179
