schedule gateway router ports on chassis having external connectivity

[venkata anil]

Currently ovn schedules gateway router ports on all chassis. Instead we need to check which chassis has external connectivity and schedule them only on these chassis. Chassis which has ovn-bridge-mappings properly configured in OVN_Southbound database will be treated as having external connectivity.

    schedule gateway on chassis with external connectivity

    Currently ovn schedules gateway router ports on all chassis.
    Instead we need to check which chassis has external connectivity
    and schedule them only on these chassis.

    Chassis which has ovn-bridge-mappings properly configured(i.e
    physnet same as gateway network physnet) in OVN_Southbound
    database will be treated as having external connectivity.
    Some network types(for example, geneve) may not use bridge
    mappings. Currently, external networks of type VLAN and FLAT
    use bridge mappings. So for these networks, we return chassis
    with proper bridge mappings and for other networks we return
    all chassis.
