Release 3.2.1

This breaks having git as a package-install in other elements. And results in diskimage-builder always erasing git on the image.

This reverts commit 3c650255.

Change-Id: Ifb18c4243aa08055d98602aa4fdb30b16dae061d

Adds:

1. grub-efi package mappings
2. efi-64 support
3. default (openrc) arm64 profile
4. systemd arm64 profile

Cleans up the keywords and use flags in 02-gentoo-02-flags.  Most stuff
was stablized.  Also cleaned up some formatting for the if statements.

Enables less trusted overlays (up to the end user to verify).

in 10-gentoo-image I cleaned up some bash lint things as well.
using && instead of -a and avoiding $?

For Bios and EFI compatibility, grub must be installed twice.
This patch adds the bios version when EFI is selected. The GPT EFI  block partitioning
already adds the bios partition, but the bootloader only called grub once.

The packages yum-utils and python-lzma have python 2 dependencies
and they're not present for Ubuntu Focal.
The package zypper should not be installed as it's not used.

NetworkManager takes a distinctly differnet network management
approach and the bulk of the dhcp-all-interfaces code is largely
targetted at distribution specific configuration. Some which may
or may not override settings, or only partially assert desirable
settings.

As such, we need to set appropriate configuration, such as the
correct client to be used, and timeouts based upon user supplied
settings.

By default this change sets the client to be dhclient on redhat
styled machines, as the packaging default, while it works for
ramdisk usage, it does not reset the interface between retries,
which can be critical if the infrastucture operator is attempting
to configure LACP trunks to the end node.

Git is a build-time dependency that should not end up in the final
image should source-repositories be the only element requiring it at
image build time.

We are at the point that all distributions we are building have Python
3, so any tools running in the chroot can assume Python 3 exists.
This makes dib-python redundant; mark it as deprecated and start to
remove it from elements where it is no longer required.

CentOS 7 is the only distro we support currently that doesn't have
Python 3 installed in some form in the base images.  For centos 7 add
an early install of it in the yum element so we can have all the
in-chroot scripts assume Python 3.  There is only one package that
causes issues; yaml which comes from EPEL.  Everywhere else it is a
base package, but we don't have a way to say "enable epel to install
this".  Just hack it in, we don't want to go reworking the world for
CentOS 7 at this point.

Also add python3 and it's yaml library to the centos 8 path.  This
brings in the "user" python3 in /urs/bin/python3 (the "system" python3
is already installed).  Again, this just lets us assume
/usr/bin/python3 in scripts for all platforms.

package-installs is one of these things running python in the chroot,
and unfortunately we have elements that use it at 01- level in
pre-installd.  Thus to make sure python3 is there nice and early, run
it at 0 level, but make sure it comes after yum/dnf update.

Other architectures are stored under "altarch" for CentOS 7, update
the match.

Convert the delimiters to "," to avoid a subtle problem with "|" --
POSIX states

  Within the BRE and the replacement, the BRE delimiter itself can be
  used as a literal character if it is preceded by a backslash.

So "s|\(foo\|bar\)|moo|" doesn't do what you might think; the inner
pipe becomes a literal | and this will *not* match "foo" or "bar".

Now that DIB is python3 only we can remove a hack that made sure
scripts outside the chroot ran with the correct version of python.
This is necessary as python3 does not resolve symbolic links to the
binary like python2.x did, which causes element scripts to fail finding
modules when DIB was run from inside a venv.

This patch does the following:
1. Reverts 9c7b8d17 which was the
   workaround for mixed python2/3 environments.
2. Updates the scripts to use "python3" instead of "python".
