class-transformer version issue

[0816i]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

The @nejsts/common package specifies class-transformer as a peer dependency with *, but it actually uses functions available from version 0.4.1.

https://github.com/typestack/class-transformer/blob/master/CHANGELOG.md

In validation.pipe.ts, the classTransformer.plainToInstance function is used, but this is actually a change included as a Breaking Change in 0.4.1.

Expected behavior

Please raise the peer dependency version of class-transformer in nestjs-common to 0.4.1 and clearly indicate that this is a Breaking change.
