Certificate is re-requested when container restarts

[gerethd]

When a container restarts the certificate is re-requested and blows through quota for let's encrypt. It would be nice to reuse the cert already mounted when the container restarts, i.e. once per pod kind of thing.

Not sure if this is possible but if someone deploys a bad deployment and leaves it, or an app crashes in the wee hours of the morning for example, i have to wait like 12 hours after i stop the continued crashed container to be able to request a new certificate.

Noticing issues with crashed containers unable to unmount the certificates since the pod no longer exists. Could to be related; if the certificates were reused after a crash.
