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 kubernetes/enhancements#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
```
