Apache is optional now, so it should not be installed as Required by the maas deb packages

[Chad Smith]

I'm trying to install on a system that has haproxy installed and I would like to optionally *not* install apache2 when installing maas.

If apache2 were only a recommended instead of required package, I could specify --no-install-recommmends to my apt install call.

When trying to install maas 1.8.2 rev 4041, I still see apache2 included in the list of packages installed, this raises errors trying to start apache with a running haproxy on my system during the maas install process.

~/$ sudo apt-get install --no-install-recommends maas

The following extra packages will be installed:
  apache2 apache2-bin apache2-data

Looking at the debian/control file for maas_1.8.2+bzr4041:

Package: maas-region-controller-min
Architecture: all
Depends: apache2,

We probably need to reduce that Depends to a Recommends if possible, or maybe there is a suggested set of packages other than the maas (meta) package that should be installed to avoid the apache dependency introduced by maas-region-controller-min.

We'll make this a recommends because most users still expect MAAS on port 80, for which they will continue to require a reverse proxy.
