ENUM_VALUE styles support: snakeCase/pascalCase

[PhilipDukhov]

Which rule and warnings did you add?

I've added config value for ENUM_VALUE.
Not everyone prefer snake case: https://discuss.kotlinlang.org/t/enum-constants-uppercase-or-camecase/13984
So there should be a possibility to choose what you prefer

Actions checklist

• Implemented Rule, added Warnings
• Added tests on checks
• Added tests on fixers
• Updated diktat-analysis.yml
• Updated available-rules.md

Fixme

Not sure how can I use different warning for each case

Awesome, thanks!!! <3
Yeah, agree with you, it should be configurable. But are you really using enums not in UPPER_SNAKE_CASE?

Well, I came to Android development from iOS, and UPPER_SNAKE_CASE for me looks crazy 😁
