    Fixed help messages for path_mtu and global_physnet_mtus options

    For path_mtu, make it clear it applies to tunnel typed tenant networks.
    Removed information about specific mechanisms used to advertise MTU
    values to instances because a) it duplicates the global_physnet_mtu
    option description; b) it is not complete now that we also advertise MTU
    via RAs. Finally, removed description for calculation details because
    they duplicate global_physnet_mtu description.

    While at it, fixed help text for global_physnet_mtus option not to refer
    to segment_mtu which was renamed into global_physnet_mtu lately.
