smp-status API certificate

Discussed in #172

Hi,

We are currently discussing how we should monitor whether the certificate we have is expired or not. Today, with the help of the smp-status page, you can see this through smp.certificate.expired, but we would like to be able to see which date it applies so you can automatically set up an alarm on it. Can you somehow get smp.certificate.expiry.date through api, for example?

Best Regards
Jonas

@jonaswest From v5.7.0 on, this can be enabled via the property smp.status.show.certificate.dates

It will result in the status entries:

• smp.certificate.notbefore
• smp.certificate.notafter

and contain dates in XSD formatting
