The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.
In the below example pods created more than 24 hours ago will be evicted.

apiVersion: "descheduler/v1alpha1"
kind: "DeschedulerPolicy"
strategies:
"PodLifeTime":
enabled: true
params:
maxPodLifeTimeSeconds: 86400

The k8s YAML manifests for deploying the descheduler as a k8s job were
duplicated across the "examples" and "kubernetes" directories and also
in README.md. This change consolidates the YAML manifests into the
"kubernetes" directory and simplifies the installation instructions for end
users in README.md.
Additionally a k8s CronJob has been added.
