* Add a connection-string based workflow to MicroStack;
* microstack add-compute command can be run at the Control node in
order to generate a connection string (an ASCII blob for the user);
* the connection string contains:
* an address of the control node;
* a sha256 fingerprint of the TLS certificate used by the clustering
service at the control node (which is used during verification
similar to the Certificate Pinning approach);
* an application credential id;
* an application credential secret (short expiration time, reader
role on the service project, restricted to listing the service
catalog);
* a MicroStack admin is expected to have ssh access to all nodes that
will participate in a cluster - prior trust establishment is on
them to figure out which is normal since they provision the nodes;
* a MicroStack admin is expected to securely copy a connection string
to a compute node via ssh. Since it is short-lived and does not
carry service secrets, there is no risk of a replay at a later time;
* If the compute role is specified during microstack.init, a
connection string is requested and used to perform a request to the
clustering service and validate the certificate fingerprint. The
credential ID and secret are POSTed for verification to the
clustering service which responds with the necessary config data
for the compute node upon successful authorization.
* Set up TLS termination for the clustering service;
* run the flask app as a UWSGI daemon behind nginx;
* configure nginx to use a TLS certificate;
* generate a self-signed TLS certificate.
This setup does not require PKI to be present for its own purposes of
joining compute nodes to the cluster. However, this does not mean that
PKI will not be used for TLS termination of the OpenStack endpoints.
Control node init workflow (non-interactive):
sudo microstack init --auto --control
microstack add-compute
<the connection string to be used at the compute node>
Compute node init workflow (non-interactive):
sudo microstack init --auto --compute --join <connection-string>

Moved security rules and keypair creation into init first.
Launch script now takes image name as positional argument, and name of
instance as a named argument. This makes it work more like launch in
other Canonical tools.
Written in Python, for ease of maintenance.
--retry and --wait args allow it to behave like tests expect it to,
while humans will get a much more intuitive (and much less noisy)
experience.
Also increased time we wait for a ping on the host, to allow for
slower, pure qemu, emulation times, and bring it in line with what
Tempest does in similar situations.

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 :-)

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.
These are instructions for runnning the demo that we're planning on
running at the Denver Openstack summit. It walks the user through
deploying microstack, and then deploying a functioning kubernetes
cloud on top of it.
