Gupta, Sangeet (sg774j) f94aed3c7a cert-rotation: New chart for certificate rotation
This chart creates a cronjob which monitors the expiry of the
certificates created by jetstack cert-manager. It rotates the
certificates and restarts the pods that mounts the certificate
secrets so that the new certificate can take effect.
