  Make the notify() calls work with IPv6 in the OCF resource-agent

When the VIP is an IPv6 address we get the following error in the
resource agent:
ovndb_servers_notify_0:355:stderr [ + ovn-sbctl -- --id=@conn_uuid create Connection 'target=ptcp\:6642\:[fd00:fd00:fd00:2000::a2]' inactivity_probe=180000 -- set SB_Global . connections=@conn_uuid ]
ovndb_servers_notify_0:355:stderr [ ovn-sbctl: ptcp\:6642\:[fd00:fd00:fd00:2000::a2]: unexpected "[" parsing string ]

This is because MASTER_IP is an IPv6 address and is being passed to
ovn-[ns]bctl without being escaped and the command errors out with
unexpected parsing string errors. The rest of the create Connection
command was already escaping the columns, we are just missing the ip
address bits in case of IPv6.

Let's make sure we escape the '[]:' characters and avoid this problem.
Tested this on an OpenStack environment on both IPv6 and IPv4.
