:type condition: ConditionBase
:param condition: A condition to be built into a condition expression
    string with any necessary placeholders.

:type is_key_condition: Boolean
:param is_key_condition: True if the expression is for a
    KeyConditionExpression. False otherwise.

:rtype: (string, dict, dict)
:returns: Will return a string representing the condition with
    placeholders inserted where necessary, a dictionary of
    placeholders for attribute names, and a dictionary of
    placeholders for attribute values. Here is a sample return value:

    ('#n0 = :v0', {'#n0': 'myattribute'}, {':v1': 'myvalue'})
