If the values for batch_size is 'choice: [1, 2, True]', it will raise
validation exception.

Additionally, use 'type(value) is int' will not pass pylint. so use
'isinstance(x, bool) or not isinstance(x, int)' to filter invalid
value(s).

Add pre-checking about the param type in choice. If user use batch_size:
[2, 4, ff] in optimizer config file, it will raise an Exception to tell
that it must be integer.
