We want to allow operators to override Horizon's default
settings. This involves moving local_settings.d out of the read only
snap filesystem, and into $SNAP_COMMON. This is a little bit tricky.

First, we patch settings.py and local_settings.py as we're building the
snap, to include a LOCAL_PATH in $SNAP_COMMON.

Then, we add a template with the rest of our default overrides,
and write it out to $SNAP_COMMON/horizon/local_settings.d

Finally we tweak our tests so that we can give our overrides a
spin. As a bonus, this makes test_horizonglogin.py a lot easier to run
in our multipass testing scenario!

`tox -e basic` now also runs selenium tests, as well.

Piped output of subprocess commands to log.

Set default log level to INFO.

Port the python2.7 local settings overrides to the python3.6 directory
structure.

Move all local_settings.py overrides into _05_snap_tweaks.py as part
of troubleshooting some remaining problems. Everything is more
organized and functional now :-)

Added selenium tests.

Move openstack-projects part from python2 to python3.

Add cloud archive.

Update qemu and libvirt versions to those from cloud archive (they
work with python3, while the distro packages versions don't).

Switch from rocky to stein.

Fetch libvirt and qemu sources via "apt source". Gets rid of sub
version hard coding in snapcraft.

Update hard coded references in tests to rocky from stein.

Written in Python. Easier to maintain. Easier to make interactive.

Renamed the old and outdated "configure-openstack" script to "init.sh"

Updated init.sh and folded most of the configure hook into it.

Removed database installation step from install hook.

We can now install microstack without a database dump, which helps
immensely in updating. And we have a logical place to put additional
configuraiton, including some of the manual steps in DEMO.md, which
could be scripted if we gave users a chance to skip the system changes
that they wanted to skip.

Also updated README and DEMO file to match new flow. Updated test
files.

Future cleanup and features documented in Trello, but not included in
this PR, which is big enough already :-)

Script now takes a "-m" argument. This helps to test locally in a
fresh environment.

Tweaked tests/basic_test.sh functional test so that it no longer
requires multpass, and can run without kvm cpu extensions being
enabled (not all machines in the game have cpu extensions.)

Added tox.ini, wrapper script for building and installation, etc.

Refactor snap to work with core18.

Giving the snapcraft.yaml a base property helps tremendously with the
efficiency of the build process, and I believe that it puts us in a
better position to reliably support non Ubuntu distros going forward.

This also bases us on long supported bionic libraries, and gives us a
nice place to work from as we add Python 3 and Stein support, as well
as general polish and fixes.

This way, it will get cleaned up when we uninstall the snap.

Also added test hooks to test upgrades, to verify that we aren't
breaking existing snaps.

Dropped a command to change the endpoints from localhost to 10.20.20.1
in the configure hook.

This is a temporary solution, pending automation of the database
update. (I was burning too much time getting a manual dump to work for
now.)

Updated the mysql tarball, which has the localhost -> 10.20.20.1
update.

Test for pinging Internet was failing due to not waiting long enough,
so added a proper retry strategy.

Addresses the issue where services such as a juju controller cannot
access endpoints from within an instance.

Updated all references to localhost to 10.20.20.1, and added the
address to ALLOWED_HOSTS.

Also updated version of qemu lib.

This is a little messy -- it's a bash script with some outside
dependencies, and it makes assumptions about the capabilities of the
environment that it's being run in. But it does basically work, and
provides contributors with some basic reassurance that they have built
a working snap.
