Code generation service

[ghost]

This enables users to handle below use cases as part of YDK app maker (YAM)

• Have netconf, restconf payload and want to migrate to YDK based app with minimal effort via tool.
• Looking for an educational channel on how to use YDK objects.
• Yang data model payload transcoding (convert XML to YDK to JSON to YDK python to .... or vice versa)

class CodeGenerationServiceProvider(object):
    """ Code generation provider"""
   def __init__(self, type):
        '''type is 'xml' or 'json' '''

class CodeGenerationService(object):
    """ Code generation service to generate code from XML/JSON payload """
   def __init__(self):
        pass
    def generate(self, provider, payload):
        '''This will return a python script snippet which can be used in a YDK app'''

It is preferable to continue using the existing service/provider abstraction
