Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

The base exception filter (https://github.com/nestjs/nest/blob/master/packages/core/exceptions/base-exception-filter.ts#L72-L75) simply drops any properties on errors other than message and stack, especially cause. This is very unfortunate as cause is when provided often crucial to understanding an error.

Minimum reproduction code

n/a

Steps to reproduce

No response

Expected behavior

Additional properties, especially cause should not simply be ignored, but forwarded to the logger.

Would you like to create a PR for this issue?

I have little understanding of what's happening with the error and why message and stack are logged explicitly. I guess the change would require more refactoring than just my simple patch, sorry.
