Olof hagsand 76e59873c2 - Changed media name: yang.collection+xml/yang to application-collection+xml/json 
- Modified ietf-netconf-list-pagination.yang:
     - changed get-pagable ->  get-pageable
     - renamed count -> limit
     - renamed skip -> offset
     - added import ietf-yang-metadata
     - added md:annotation remaining
