Revert "Generate ovn-chassis-mac-mappings on ovn-controller group"

Browse Source 
This reverts commit 8bf8656dba.

Reason for revert: Setting ovn-chassis-mac-mappings on network nodes 
is causing mac flooding [1] [2] for traffic between external ports, 
and very slow troughput in consequence.
OVN HA Chassis priorities between gateways should probably be managed
by Neutron [3]

Fixes ``ovn-chassis-mac-mappings`` missing on network nodes.
Previously ``ovn-chassis-mac-mappings`` has been added only to
``ovn-controller-compute`` group. However external ports are being
scheduled on network nodes. Adding ``ovn-chassis-mac-mappings``
on whole ``ovn-controller`` group fixes the bug.
