VXLAN tunnel_type changes deprecated enable_tunneling in the agent incorrectly

[Kyle Mestery]

The change to add VXLAN support into the OVS plugin [1] deprecated enable_tunneling in the agent, but did so such that it was not backwards compatible. What needs to be done is to mark this option as deprecated so it goes away in the Icehouse release, and to modify the create_agent_config_map() to default to GRE tunnels if the user configures this option in Havana.

    Deprecate enable_tunneling in the OVS agent

    This patch properly deprecates the 'enable_tunneling' option in the OVS agent.
    It does this be ignoring it if 'tunnel_types' is set, and if 'enable_tunneling'
    is set, it defaults 'tunnel_types' to only GRE.

    Fixes bug 1195374
