Move instead of copy the temporary git manifest

This prevents a build-up of temporary files in the cache directory

Add switch to turn on caching for debian element.

DIB_OFFLINE has wide-ranging effect. This patch adds a tunable that
only turns on the tarball-caching behaviour specifically for the
debian element.

Remove the temporary deploy element after rename

This is dependent upon change in tripleo-incubator
I1ff4bb98c99dfe87ccc4fb19767b93e27707d3a7 and concludes the
renaming of deploy to deploy-baremetal

The rename was performed so that each element had a more descriptive
name, and so that each element could accurately set an element-provides
of "deploy", given that the elements enable tripleo deploys via the
ramdisk image.

Specifically, it adds a sysv init script and the relevant install/config steps.

Tested with Debian jessie/testing.

debian: support upstart on Wheezy

Upstart cannot be installed by debootstrap on Wheezy because of a
conflict with sysvinit. sysvinit is flagged a being “essential” and
apt-get will refuse to remove it.
See: https://bugs.debian.org/668001

This patch uses another strategy. We install a standard sysvinit
Debian chroot with debootstrap and during a second step, we
replace sysvinit with the wanted init system.

Debian.

A backport of systemd is used on Debian Wheezy.

debian: properly deal with Debian stable/unstable

This commit fixes the if/else block around Debian stable/unstable which
was badly merged during the last rebase.

Build raw image in separate tmpfs

If the tmpfs being used to hold the image filesystem is close to being
full then housing the raw disk image in the same place can be
problematic as it tends to grow faster then the filesystem shrinks when
data is being moved into it.

Putting them both into separate tmpfs's will allow there to be an
overlap where they jointly use more then the size limit for a singe tmpfs.

Closes-Bug: #1289582
Support declarative package installs/uninstalls

Adds a new element, package-installs, that provides an interface for
declarative package installs and uninstalls. Packages to install can be
added to an install.d/package-installs-<element-name> file. The set of
packages listed across such files are installed in a single transaction
at the beginning of install.d.

Prefacing the package name with a "-" indicates that the package should
be uninstalled at the end of the install.d phase. Again, the full set of
uninstalls are done in a single transaction.

An element providing a package-installs file should add package-installs
to its element-deps file.

Allow excluding tests from certain files

There are certain scripts (such as the ramdisk init script) that
need to ignore linting rules for one reason or another.  This adds
support for exclusions via a comment in the file like:

"# dib-lint: disable=executable sete"

There should be no ", but I need those to prevent git from treating
that as a comment.  This syntax is similar to the pylint exclusion
mechanism.

Exclusion support is added to the executable check, but not
the alphabetical ordering one because I can't imagine a reason we
would need to disable that, and I don't know that comments are
supported in those files anyway.

Make sure all scripts are set -e

If scripts are not set -e then errors can be ignored, causing more
confusing failures later.

Also adds an exclusion comment to the ramdisk init script since we
don't want that to exit on failure.

Add map-services for debian distros.

DIB's map-services is currently used in TIE's os-svc-config
binaries to support service name lookups. Many of the systemd
specific functions require bin/map-services to exist.

This change adds bin/map-services files that are noops
to both the debian and ubuntu elements so that as those
distros move towards using systemd they can make use
of the functions we already have in place.
