OVN: Remove environment files which deploy OVN dbs in non HA

Browse Source 
In a 3 node controller deployment OVN db servers are started only on one node
and if that node goes down, we hit the down time for ovsdb-servers and neutron-server.

So it is highly recommended to deploy OVN db servers as a pacemaker HA resource.

Removed environment files to deploy OVN db servers in non HA mode for OVN
deployments as it is not recommended. There is no support to upgrade an existing
OVN deployments from non HA to HA. It is recommended to have a fresh deployment.
To deploy OVN with dvr support, use environment/services/neutron-ovn-dvr-ha.yaml,
otherwise use environment/services/neutron-ovn-ha.yaml
