Expose whole Class

[jianzhou520]

Description

The default behaviour of the plainToClass method is to set all properties from the plain object, even those which are not specified in the class.In our case, we make some Class as a validator, so other unknown properties are dangerous

Proposed solution

like @exclude() working whole Class, maby @expose() can do the same thing, otherwise we need add @expose() before every properties in validator Class

This will be great option to have. The library should allow us to turn on this feature when, for example, we call plainToClass function.
I have an object with 500 total fields, I have to add @Expose in each and every property 😢
