New Rule Agent

[FFawzy]

• adding a new agent that has the capability-ish to add new validator rules
• might not be perfect this is still the first try but can/should be enhanced to be able to do it alone
• I tested on one example provided by @mo-alras and you can see the results already in the PR

EnumValuePascalCaseRule

@jenschude maybe tell me what are the wrong things it did here and we can instruct the agent to do better next time
