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.

There's some relevant discussion in #2705 (comment):

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.
