82cfcfe551 Add ensure-venv element, install glean with it
All the platforms we care about now have python3 with venv (even
centos7 now) packaged somehow.  Add an ensure-venv element to make
sure that "python3 -m venv" works.  Any other elements that wish to
install non-distribution-packaged Python utilities can use this to
keep them separate from the main system installs.

Port glean to use this, and drop its dependency on pip-and-virtualenv.

643415f366 simple-init: Use wrappers to call pip for glean install
Use the wrapper calls from Ia267a60eecfa8f4071dd477d86daebe07e9a7e38
to install glean.

Using this wrapper means we cover all cases without more and more
branches; it should work for python2, python3 and also the special
case of RHEL/CentOS where dib-python points to the special
/usr/libexec/platform-python (which is python3.6 with inbuilt pip)

daf5a4e4bd Switch simple-init to support python3
Depending on the version of $DIB_PYTHON_VERSION, we can either use pip /
pip3 to install glean.  This is helpful for newer OSes that might not
want to ship python2 (pip).

8ec3750dda simple-init: allow for NetworkManager support
This plumbs through an "--use-nm" flag to glean which instructs it to
setup interface bringup with NetworkManager rather than legacy network
enablement scripts.

In this case, install the NetworkManager package.  In the non-nm case,
also install the network-scripts for Fedora 29 -- this has stopped
being installed by default (it's been deprecated since forever).

As noted in the docs, this is currently really only relevant on the
supported rpm distros which are using the ifcfg-rh NetworkManager
plugin to effectively re-use old config files.  However,
NetworkManager has similar plugins for other platforms, so support can
be expanded if changes are proposed.

11d91501d0 Fix /etc/network/interfaces file contents
According to http://bit.ly/2HA4oDO and
the official Ubuntu manual
http://manpages.ubuntu.com/manpages/xenial/man5/interfaces.5.html
source-dir support has been removed from Ubuntu >= 16.04/Xenial

Once an image is generated and booted, moving the dhcp interface(s)
declaration(s) from /etc/network/interfaces into specific subentries
of /etc/network/interfaces.d and calling 'service networking restart'
just make your instance unreachable and all interfaces are left
unconfigured.

This patchset fixes this issue

97c01e48ed Move elements & lib relative to diskimage_builder package
Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).

The problem with this is that editable/development installs (pip -e)
do *not* install data_files.  Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.

data_files is really the wrong thing to use for what are essentially
assets of the program.  data_files install works well for things like
config-files, init.d files or dropping documentation files.

By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from.  In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].

We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.

Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.

I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.

Unfortunately, this has to move to work with setuptools.  You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.

[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do.  Essentially for us it's returning
__file__.
