Checkmk Werk 10709: Fix site certificate being overwritten during version update

ID: 10709 Title: Fix site certificate being overwritten during version update Component: Site Management Level: 1 Class: Bug fix Version: 1.6.0p9 The sites SSL certificate (etc/ssl/sites/[site].pem), which is used by encrypted livestatus communication, was replaced with a fresh certificate during each "omd update". When using certificates issued by the site CA, this was not an issue, because the trust at the central site was established with the site CA. It was only an issue when trying to replace the site certificate with a certificate signed by an external CA.
