Make Ubuntu Vagrant box 40G. (LP: #1580596 )

Vagrant images were previously put at 10G, but this was a regression
from Trusty, in which they were 40G.  This made it a tough sell for
users to upgrade if they were using a Ubuntu desktop experience.

This change does not impact disk usage as Vagrant with the virtualbox
provider dynamically allocates space with the VMDK.  On a test system,
the VMDK took up 1.1G of disk space according to df, and after
creating a 2G file in Vagrant, the VMDK grew to 3.1G.

Therefore, users who are running on a system with little free space will
not see adverse effects if they upgrade to a new vagrant image

ubuntu-cpc: parallel builds

* Replace "snap download" with tool that uses snap store's coherence feature

    This is important for parallel image builds to ensure all pre-seeded snaps
    have the same versions across image variants.

* Inject a proxy into the build providing a snapshot view of the package repo.

    When the REPO_SNAPSHOT_STAMP variable is set, the auto/build script will attempt
    to launch a transparent HTTP proxy on port 8080, and insert an iptables rule to
    redirect all outgoing HTTP requests to this proxy.

    The proxy, contained in the `magic-proxy` Python script, examines each request
    and silently overrides those pointing to InRelease files or files that are
    listed in InRelease files. It will instead provide the contents of the requested
    file as it was at REPO_SNAPSHOT_STAMP, by downloading the corresponding asset
    "by hash".

* Use series files with dependency handling to generate hook symlinks dynamically

    This patch currently only applies to the "ubuntu-cpc" project.

    More and more logic has been going into the hook scripts to decide
    under which conditions they should run or not. As we are moving
    to parallelized builds of image sets, this will get even more
    complicated. Base hooks will have to know which image sets they
    belong to and modification of the dependency chain between scripts
    will become more complicated and prone to errors, as the number of
    image sets grows.

    This patch introduces explicit ordering and dependency handling for
    scripts through the use of `series` files and an explicit syntax
    for dependency specification.
