Support Probe-level `terminationGracePeriodSeconds`

[andrewpage]

Description

Kubernetes >v1.25 supports a terminationGracePeriodSeconds field on livenessProbe and startupProbe. This field overrides the Pod-level terminationGracePeriod field when a SIGTERM is triggered by a probe failure.

Probe-level terminationGracePeriodSeconds cannot be set for readiness probes.

Potential Terraform Configuration

resource "kubernetes_deployment" "example" {
  metadata {
    # ...
  }

  spec {
    # ...

    template {
      # ...

      spec {
        container {
          # ...

          liveness_probe {
            # ...

            termination_grace_period_seconds = 3
          }
        }
      }
    }
  }
}

There's some relevant discussion in https://github.com/hashicorp/terraform-provider-kubernetes/issues/2705#issuecomment-2736679918:

We're working on a comprehensive solution to cover all of the missing attributes consistently, through code generation.

Hopefully this solution can be released soon.
