This series adds support to run multiple ovn-controller instances using
the same vswitchd instance. This may be used to reuse a single host
level vswitchd installation to run multiple CMS (e.g. k8s and
openstack), each having its own OVN stack running on a separate
integration bridge.
This setup may, in some instances, simplify administration of the
system, since the admin no longer needs to maintain separate vswitchd
installations (e.g. in separate containers). This is also helpful when
running different datapath types for the mixed setup.
v1: initial series
v2: change tunnel port naming scheme: include "chassis index" instead of
its name for source chassis.
v2: formatting adjustments.
v3: fixed build due to ovs_abort missing arguments.
v3: added documentation to CLI and system-id-override file.
v3: added documentation for chassis specific db config options.
v3: documented the ability to run multiple controllers on the same host,
while mentioning that this support is highly experimental.
v3: updated NEWS file to include the note about the new experimental
issue.
v3: rebased.
v4: fixed a memory leak in get_chassis_idx.

Support ovn-...-<chassis> specific global ovsdb options
Allow to override system-id via file
Support passing chassis name via CLI
Don't touch tunnel ports from a different br-int
Add connectivity test for 2 controllers on the same host
Document experimental support for co-hosted controllers
