Cleanup of HTTP_Codes

Pull request type

Please check the type of change your PR introduces:

• Bugfix
• Feature
• Code style update (formatting, renaming)
• Refactoring (no functional changes, no API changes)
• Build related changes
• Documentation content changes
• Other (please describe):

What is the current behavior?

• A lot of modules overwrite the generic HTTP-Codes in utils.py with very similar or even equal ones

What is the new behavior?

• module utils got updated with more HTTP-Codes and other ones have been updated
• Removed a lot of redundant HTTP-Codes in the modules
• Changed the fetch-function in the api so it works also without any additional http-codes

Other information

Some modules use extra http-codes that are adapted to the module (e.g. 200 - "Folder created" in the module folder).
Maybe we should discuss, if either other modules should use customized messages too.
As example for the bakery: "200: Agents have been baked" instead of "200: OK: The operation was done successfully"
Or we use also the generic version in other modules.

First one would end up in more code to take care of, but is nicer to read.

I like that idea. :-)
There's only a minor change request from my side.
