Inherited classes not initialized properly in Python3 when constructor uses super()

[ygorelik]

Current Behavior

Inherited classes are not initialized properly in Python3 when constructor uses super().

Example from errors.py:

class YServiceError(YError):
    '''
    Exception for Service Side Validation
    '''
    def __init__(self, error_code=None, error_msg=None):
        super(YServiceError, self).__init__(
            error_code=error_code, error_msg=error_msg)

This code works fine in Python2, but python3 requires different syntax:

class YServiceError(YError):
    '''
    Exception for Service Side Validation
    '''
    def __init__(self, error_code=None, error_msg=None):
        super().__init__(
            error_code=error_code, error_msg=error_msg)
