While OVS was used initially due to availability of a
networking-generic-switch driver for it, Linux bridge can be useful for
environments where OVS is not available.
This is configured via bridge_type variable. It defaults to
'openvswitch', but may be set to 'linuxbridge'.

This change modifies the deploy-teardown jobs to use python 3 in the
local virtualenv in which ansible is installed. It also switches to use
python 3 on Ubuntu remote hosts via ansible_python_interpreter. Python
3 support for CentOS remote hosts will be added with CentOS 8 support.

Open vSwitch packages are no longer present in the default, or EPEL
repoistories. This means there is no clean way to install Open vSwitch
on CentOS. Instead, we should leave it up the user to decide how to
install it.

If the ironic_config field is not present in a node definition, then
that node should not be registered with ironic. In this case we also
don't need to query glance for images or wait for resources to appear
in placement.
If nova_flavors is empty, we do not need to register flavors, so no need
to install the client or check for OS_USERNAME.
Also fixes an issue in the action plugin where it would fail if
ironic_config field is not present in a node definition.
Finally, in CI deploy/teardown tests, rather than skipping tasks, we now
remove the ironic_config field from the node definition, and set
nova_flavors to empty, such that we exercise these code paths.
