Add changedetector functionality for ${SSL_TYPE} == manual (#2404)
Now, setups that use `SSL_TYPE=manual` will profit from the changedetector as well. Certificate changes are picked up and properly propagated.

### `SASLAUTHD_LDAP_FILTER`
|
||||
|
||||
This filter is used for `saslauthd`, which is called by postfix when someone is authenticating through SMTP (assuming that `SASLAUTHD_MECHANISMS=ldap` is being used). Note that you'll need to set up the LDAP server for saslauthd seperately from postfix.

|
||||
|
||||
The filter variables are explained in detail [in the `LDAP_SASLAUTHD` file](https://github.com/winlibs/cyrus-sasl/blob/master/saslauthd/LDAP_SASLAUTHD#L121), but unfortunately, this method doesn't really support domains right now - that means that `%U` is the only token that makes sense in this variable.
