Subject: [PATCH] Add a debian-mirror element

Add a new element that will set up and configure a Debian or Ubuntu
mirror. It will not populate the mirror during image creation, but
will do so after it is deployed.

+Installs apt-mirror from packages.
+
+Please note that Debian or Ubuntu mirrors are very large -- a single
+architecture of a single series is roughly 50GiB, and a full Ubuntu archive
+is on the order of 600GiB -- so please keep in mind when you attach storage.
+
+Configuration
+-------------
+
+    debian-mirror:
+      mirror: "http://archive.ubuntu.com/ubuntu"
+        # The mirror you wish to mirror from.
+      suites: ["saucy", "saucy-updates", "saucy-security"]
+        # An array of suites you wish to mirror, such as `saucy' or `wheezy'.
+      architectures: [{"arch": "amd64"}]
+        # An array of dictionaries containing the architectures you wish to
+        # mirror.
+      components: ["main", "restricted", "universe", "multiverse"]
+        # An array of components you wish to mirror, such as `main' or
+        # `non-free'.
