Initial basic bootstrap-checkpoint support **What this PR does / why we need it**: Adds initial support for Pod checkpointing to allow for controlled recovery of the control plane during self host failure conditions. fixes #49236 xref https://github.com/kubernetes/features/issues/378 **Special notes for your reviewer**: Proposal is here: https://docs.google.com/document/d/1hhrCa_nv0Sg4O_zJYOnelE8a5ClieyewEsQM6c7-5-o/edit?ts=5988fba8# 1. Controlled tests work, but I have not tested the self hosted api-server recovery, that requires validation and logs. /cc @luxas 2. In adding hooks for checkpoint manager much of the tests around basicpodmanager appears to be stub'd. This has become an anti-pattern in the code and should be avoided. 3. I need a node-e2e to ensure consistency of behavior. **Release note**: ``` Add basic bootstrap checkpointing support to the kubelet for control plane recovery ``` /cc @kubernetes/sig-cluster-lifecycle-misc @kubernetes/sig-node-pr-reviews |
