[ovs-dev] Creation of network using ovs in Docker

That is a different ovsdb-server (used for OVS). The ovsdb-server used for
OVN databases does not look to be running. OVS 2.5.2 is very old and I am
not sure what is causing this behavior. You can look at logs in
/var/log/openvswitch/ovsdb-server-*.log for hints. I suggest to move to OVS
2.9.2.
