Basic components to assist with error handling and adhere exceptions to the Api spec

[silentninja]

Problem

We need a basic set of components to help with converting existing exceptions to new error spec.

1. A exception handler that is able to capture all exceptions and provide the ability to extend as needed
2. Error structure that conforms to the API spec to be used when constructing an error
3. Error code unique Enum to refer to

Proposed solution

1. We can override the default Drf exception handler which allows us to capture any exception that is thrown
2. NamedTuple looks like a good candidate
3. Enum with unique decorator
