Since OVN 20.06 [1], the OVN configuration is stored in
"Chassis.other_config".
Since OVN 22.09, the "Chassis" configuration stored in
"Chassis.other_config" will not be replicated to
"Chassis.external_ids".
The ML2/OVN plugin tries to retrieve the "Chassis"
configuration from the "other_config" field first; if this
field does not exist (in OVN versions before 20.06), the plugin
will use "external_ids" field instead. Neutron will be compatible
with the different OVN versions (with and without "other_config"
field).

NOTE: this patch is similar to [1], but in this case neutron keeps
compatibility with the different OVN versions (with and without
"other_config" field). Since [2], the Neutron CI has a new job that
uses the OVN/OVS packages distributed by the operating system
installed by the CI (in this case, Ubuntu 20.04 and OVN 20.03).
