Segment routing sensors OpenConfig compliance

We now support OpenConfig compliant resource paths for the segment routing SID ingress sensor. Use the new resource paths to export statistics using UDP, Juniper proprietary Remote Procedure Call (gRPC) or gRPC Network Management Interface (gNMI). For example, the new OpenConfig compliant resource path /network-instances/network-instance/mpls/signaling-protocols/segment-routing/aggregate-sid-counters/aggregate-sid-counter/mplslabelreplaces /mpls/signaling-protocols/segment-routing/aggregate-sid-counters/aggregate-sidcounter/state/mpls-label. If you are using UDP for export, the new OpenConfig compliant resourcepath /network-instances/network-instance/mpls/signaling-protocols/segment-routing/aggregatesid-counters/ replaces the resource path /junos/services/segment-routing/sid/usage/. This feature also supports initial sync, a feature that samples all statistics for a subscription from a device, then only exports statistics that change.
