Add cacheConfig, setter process, getter script

[CJA18]

A few general things you need to do when committing to TorQ:

• The PR needs a more detailed description outlining the reason for it, what's being achieved, future steps to come etc
• A lot of these functions seem to be something common that has likely been done already and might have an existing util function, always check for this first as it's best practice to reuse the existing utils (if something needs to be changed then it only needs to be changed in one place)
• Follow coding standards, if you look at the rest of the codebase camelCase isn't used so follow whatever standard is used in the codebase
• For comments, in the rest of the codebase you'll see that the comments are generally block comments for each function describing what the function and each step in the function is doing, and inline comments are used in special cases (check the codebase to see when to use them)
• You committed an empty json config file, it's better to commit a file with some defaults so a reviewer can get an idea of what it will be used for
