Autocli does not offer completions for leafref to identityref

[pheller]

Given the yang module openconfig-bgp, where a bgp neighbor may have multiple afi-safis configured, the afi-safi list is defined like so:

list afi-safi {
      key "afi-safi-name";

      description
        "AFI,SAFI configuration available for the
        neighbour or group";

      leaf afi-safi-name {
        type leafref {
          path "../config/afi-safi-name";
        }
        description
          "Reference to the AFI-SAFI name used as a key
          for the AFI-SAFI list";
      }

And, the leafref for afi-safi-name points to:

leaf afi-safi-name {
      type identityref {
        base oc-bgp-types:AFI_SAFI_TYPE;
      }
      description "AFI,SAFI";
    }

Ideally, the leafref would offer the same completions as offered by the identityref leaf, and furthermore would not allow non-conforming entries.

After reading RFC 7950 more thoroughly, several leafref issues needed to be modified, where the problem reported in this issue is a sub part. The larger issue was to move the typecheck/validation/completion from the "referring" node (the leafref) to the "referred node) (the identityref in this example.

Looks good, thanks!
