This overlaps a little bit with some of the existing work on SyftSerializable. Might want to confer with @tudorcebere on this one.

@shubham3121 We might be able to achieve this with existing work, could you describe what is the end goal of this class? (Where/why is it needed?)

[shubham3121]

@tudorcebere this class can be used by libraries like Syfer text to register classes that needs to be serailized. Refer to this issue #3626

@karlhigley Closing this PR as @tudorcebere is already working on the improvement.
