Add the ability to lock on ConfigMaps to support HA for self hosted components

**What this PR does / why we need it**:
This PR add the ability to lock on ConfigMap objects.  As we self-host more and more components, ConfigMaps provides a useful resource to lock on that applies to just the component that is being added.  

This allows components such as scheduler+controller manager, etc. to have a simple mechanism to allow to active-passive HA without the cost of endpoint updates.

**Special notes for your reviewer**:
We may want to deprecate endpoints locking at some point. 

**Release note**:
```
