[ODTN]add NETCONF driver for Infinera and OPENCONFIG handler

Handler can easily create List<CharSequence> of OPENCONFIG by managing
ModelObject and Annotation together.
Handler also gives an alias to ModelObject of the same name in another
package(eg DefaultConfig), making it easier to handle within the same
class.
