OVN: The ovn-nb-db-server and ovn-sb-db-server scripts don't handle schema updates

[Numan Siddique]

It is better to use ovn-ctl script [1] to start OVN ovsdb-servers as this script takes care of creating the database from the schema,
updating the database from the schema when the schema version gets updated.

This script is also used by OVN systemd services to start OVN services.

[1] - https://github.com/ovn-org/ovn/blob/master/utilities/ovn-ctl for newer OVN versions and https://github.com/openvswitch/ovs/blob/branch-2.11/ovn/utilities/ovn-ctl for older versions.

    Use ovn-ctl script to start OVN ovsdb-servers

    Using the ovn-ctl script to start the OVN ovsdb-server is the better
    way. This script is used to start and stop all OVN systemd services.
    This script takes care of creating the database from the schema,
    updating the database from the schema when the schema version gets
    updated.

    The present scripts - start_nb_db_server.sh and start_sb_db_server.sh
    doesn't take care of schema updates.

    With this, we don't need extend_start.sh in ovn-nb-db-server/ovn-sb-db-server
    to create the database from the schema.

    This patch also deletes kolla_ovn_extend_start from the ovn-base image as it
    is not required.
