How to reproduce issue

Update bind_plugin.inc.php to correct "PHP Parse error:  syntax error, unexpected ':' in /usr/local/ispconfig/server/plugins-available/bind_plugin.inc.php on line 279"

Wrong table used to remove deleted backup record for website. File gets removed but not database record.

Do not add www as subdomain to a letsencrypt ssl cert when the domain of the webiste is already www.example.com (and not example.com) even if auto subdomain is set to www.

This reverts commit 7827db36

- remove certificate renew config on domain deleting

- added 'certbot' to which command (if letsencrypt is not installed as system package, but certbot is)

add optional arrays for service-name to function system->getinitcommand and also a parameter to check if the current service exists (mandatory if you use an array)
