[CHORE] Adopt Naming Convention for Scorers

[nkpng2k]

As Per Comments Here:
#156 (comment)

Is a good idea to restructure this repository to adopt a naming convention for scorers. This will help to avoid confusion and also make the repository easier to manage.

personally, I'd advocate for nested dirs if possible, however, @osery comment suggested something similar to rest-scorer-local and rest-scorer-aws-lambda which would also work (and be less difficult to implement, since it more or less comes down to renaming dirs and projects. 😄 )

|-- aws
    |-- lambda
    |-- sagemaker
|-- gcp
    |-- cloud-run
|-- azure
|-- local

Generally, I agree 👍.

But I am afraid that I will not be able to implement this due to my leaving the company end of Feb :-(.
