I stumbled upon an issue with the Alertmanager that required
an additional comand line option. See https://groups.google.com/forum/#!msg/prometheus-users/-5wd-P13xCI/lGLBHHgnBgAJ

 * acquire DHCP on the interfaces with networking.interface.$name.useDHCP == true or on all interfaces if networking.useDHCP == true (was only only "eth0")
 * respect "mtu" if it was in DHCP answer (it happens in the wild)
 * acquire and set up staticroutes (unlike others clients, udhcpc does not do the query by default); this supersedes #41829

10G is not enough for a desktop installation, and resizing a Virtualbox disk image is a pain. 
Let's increase the default disk size to 100G. It does not require more storage space, since the empty bits are left out.

This attempts to improve stability of the test by using existing
services for miniupnpd and transmission.

It also uses explicit addresses for the network interfaces so that the
external IP addresses are valid internet addresses (thus fixing
validation problems from upnpc).

Also disable eth0 from being used to transfer torrents over without that
being the intention.

Dovecot has its own SASL implementation,
but needs Cyrus SASL's headers to bind to an LDAP server using SASL.

This is useful to avoid the need to manage a dnpass= in dovecot-ldap.conf
by using the Unix socket to authenticate.

This is done with sasl_mech=EXTERNAL in dovecot-ldap.conf, and some olcAccess: with
 by dn="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
in the slapd's cn=config for the LDAP database queried by dovecot/auth (which runs as root).

The `unfree` and `unfreeRedistributable` licenses both have `free = false`,
which will trigger the first portion of logic. This removes dead code to
simplify the logic.

As a follow-up, I plan to add an attribute `redistributable = [true|false]`,
which can be used by Hydra to determine whether a given package with a given
license can be included in the channel.
