Hey @s1ntaxe770r, Can you please make the appropriate chanegs to the yaml files under pkg/KubeArmorHostPolicy , pkg/KubeArmorPolicy and deployments/ to include liveness probes. except that, the pr LGTM.

@achrefbensaad re-review pls?

[achrefbensaad]

everything looks in place, except manifests under geeneric should be automatically generated.

• add the heath checks under objects.go
• run make to generate a new manifest under generic folder.
