### Motivation
* While component certs can be configured with a custom duration the CA cert for self-signed configuration uses default values. It can be convenient to have this certificate expire more than a month out.
### Modifications
* Updates the internal issuer `{{ .Release.Name }}-ca-tls` certificate to make `duration` and `renewBefore` configurable. Does not use `common` so that the CA can be configured to last much longer than individual components certs if desired.
