* YANG Leafref feature update

* Closer adherence to RFC 7950. Some of this is changed behavior, some is new feature.
  * Essentially instead of looking at the referring leaf, context is referred(target) node
  * Validation uses referred node
    * Validation changed to use type of referred node, instead of just "string"
  * Auto-cli
    * Changed to use type of referred node for typecheck
    * Completion uses referred node
  * Required instance / less strict validation
    * New: Leafrefs must refer to existing data leaf ONLY IF YANG `required-instance` is true
    * Previous: All leafrefs must refer to existing data leaf node
* Fixed: [Autocli does not offer completions for leafref to identityref #254](https://github.com/clicon/clixon/issues/254)

* See changes under new feature "YANG leafref feature update"
* Validation of referred node type (not referring)
* Leafref required-instance must be set to make strict data-node check
* Native Restconf is now default, not fcgi/nginx
