minimal changeset to get things working on 18.04 @joshdata squashed pull request #1398, removed some comments, and added these notes: * The old init.d script for the management daemon is replaced with a systemd service. * A systemd service configuration is added to configure permissions for munin on startup. * nginx SSL settings are updated because nginx's options and defaults have changed, and we now enable http2. * Automatic SSHFP record generation is updated to know that 22 is the default SSH daemon port, since it is no longer explicit in sshd_config. * The dovecot-lucene package is dropped because the Mail-in-a-Box PPA where we built the package has not been updated for Ubuntu 18.04. * The stock postgrey package is installed instead of the one from our PPA (which we no longer support), which loses the automatic whitelisting of DNSWL.org-whitelisted senders. * Drop memcached and the status check for memcached, which we used to use with ownCloud long ago but are no longer installing. * Other minor changes.

set ssl_stapling_verify back to on, reverts part of 47de93961e88d3790120caeece0648ed6ab2c44c The sslmate guidance changed. See #458.

ssl_stapling_verify on;
OCSP improvements * Set ssl_stapling_verify to off per https://sslmate.com/blog/post/ocsp_stapling_in_apache_and_nginx ('on' has no security benefits). * Set resolver to 127.0.0.1, instead of Google Public DNS, because we might as well use our local nameserver anyway. * Remove the commented line which per the link above would never be necessary anyway. OCSP seems to work just fine after these changes.
