* drop the ondrej/php PPA since PHP 7.x is available directly from Ubuntu 18.04
* intall PHP 7.2 which is just the "php" package in Ubuntu 18.04
* some package names changed, some unnecessary packages are no longer provided
* update paths
@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.

This reverts commit 82844ca651 ("make certbot auto-agree to TOS if NONINTERACTIVE=1 env var is set (#1399)") and instead *always* auto-agree. If we don't auto-agree, certbot asks the user interactively, but our "curl | bash" setup line does not permit interactive prompts, so certbot failed to register and all certificate things were broken until the command was re-run interactively.
Starting with 2.4, Z-Push no longer provides tarballs on their download server. The only options are getting the code from their git repository or using one of their distribution packages. Their Ubuntu 18.04 packaes don't seem to actually work in Ubuntu 18.04, so thinking ahead that's currently a bad choice. In 78d1c9be6e we switched from doing a git clone to using wget on their downloads server because of a problem with something related to stash.z-hub.io's SSL certificate. But wget also seems to work on their source code repository, so we can use that.
git clone (which uses curl) underneath was failing. Curiously, the same
git clone command would work on my macos host machine.
From the screenshot it looks like curl was somehow not able to negotiate
the connection. Might have been a missing CA certificate for Comodo, but
I was not able to determine if that was the issue.

Our wget_verify function uses wget to download a file and then check
the file's hash. If wget fails, i.e. because of a 404 or other HTTP
or network error, we exited setup without displaying any output because
normally there are no errors and -q keeps the setup output clean.
Wrapping wget with our hide_output function, and dropping -q, captures
wget's output and shows it and exits setup just if wget fails.

Passwords must be eight characters long; when passwords are changed via the users page the dialog states that passwords need to be at least four characters but only eight or more are acceptable.
