Code Issues Proposed changes

Rework the test framework & the clustering test 

* Remove the dead code;
* Rework the test types;
* Restore the instance connectivity check;
* Rework the clustering test to support the new node addition workflow;
* Check whether a machine where MicroStack is installed has hardware
  virtualization capabilities for different architectures. If not, use
  software emulation;
  * the host model is used with KVM since the default QEMU CPU models on
    x86_64 are subject to vulnerabilities without certain CPU-specific
    features. This conflicts with being able to use live migration
    reliably across hosts with different CPUs.
* Add a default-source-ip init argument to allow controlling the source
  IP of the installation host that will be used as a control ip or
  compute ip locally.
  * used in the clustering test so that the local host IP on the
    multipass network is used as a control IP instead of the IP
    through which the default gateway is available;
  * the IP through which the default gateway is accessible is
    used as a fallback for default-source-ip;
* Given upstream CI has a low amount of resources allocated per machine
  use LXD to set up a dummy compute node;
  * Set RLIMIT_MEMLOCK to 'unlimited' in the LXD container profile
    (see the discussion in LP: #1906280);
  * set remember_owner to 0 in qemu.conf for libvirt to avoid the
    uses of XATTRS (the root user is used anyway so there is no
    need to remember a file owner), otherwise libvirt errors out
    in an unprivileged LXD container.
* Use numeric versions of OpenStack packages in the python-packages
  section of the openstack-projects part since the resolver change in
  recent versions of pip disallows for constraints dependencies of
  packages that come from a URL or a path.
  https://github.com/pypa/pip/issues/8210
  * The newest released version of pip is always used during builds
    since snapcraft uses venv to set up virtual environments and the
    ensurepip package is invoked such that a pip version shipped with
    the distro version of python is upgraded:
    https://github.com/python/cpython/blob/3.8/Lib/venv/__init__.py#L282-L289
            cmd = [context.env_exe, '-Im', 'ensurepip', '--upgrade',
                                                    '--default-pip']
  * Environment variables are ignored when pip is installed in the venv:
    https://docs.python.org/3/using/cmdline.html#id2 (-I option)
    So there is no way to use the old pip version resolver.

Minor clustering client and add-compute changes:

* use stderr for diagnostic messages;
* use stdout to output the connection string so that it can be easily
  picked up by CLI tools without parsing.
