Potentially wrong parameter type in Custom Dimension service - deleteCustomDimension method

[akurdyk]

In Custom Dimension service function deleteCustomDimension have parameter customDimensionId typed as string but rest of the functions type that param as string | number. In the JavaScript client documentation there is another version that param should be number. I guess it should be unified.
