Description

What is the feature and why do you need it:

Currently, the K8S Python API only supports leader election using ConfigMapLock.

The K8S Go API supports using the proper Lease resource type with its LeaseLock, and actually recently removed support for the legacy ConfigMap approach.

We should update the Kubernetes Python API to provide a Lease-based leader election.

Contributor guide

Research direction
Study the existing ConfigMapLock implementation in the Python client, review the LeaseLock implementation in the Go client, and understand the Kubernetes Lease resource API. Implement a new LeaseLock class following the same pattern.
