Experimental Kotlin plugin to support Lombok annotations in the same compilation unit with kotlin

Features support:

[~] Config files

• [x] Basic support - single config file. Need to be specified explicitly by plugin config
• [ ] Import other config files
• [ ] Config files discovery and bubbling

[~] @Getter/@Setter

• [x] Basic support
• [x] Class-level
• [x] @Accessors config support: chain and fluent
• [~] Config support
  • [x] lombok.getter.noIsPrefix
  • [x] lombok.accessors.fluent
  • [x] lombok.accessors.chain
  • [x] lombok.accessors.prefix
  • [ ] lombok.noArgsConstructor.extraPrivate (probably we don't need to support it - it is private after all)
  • [ ] lombok.copyableAnnotations (probably don't need it)
• [ ] Copy annotations
• [x] Strip defined prefixes - in config and @Accessors
• [x] Skip generation with AccessLevel.NONE
• [x] Strip ‘is’ prefix for boolean fields

[~] @With

• [x] Basic support
• [ ] Copy annotations (probably don‘t need it, because annotations don’t affect members' resolution)

[x] @NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructor

• [x] @NoArgsConstructor
• [x] @AllArgsConstructor
• [x] @RequiredArgsConstructor

[x] @Data

[~] @Value

• [x] generate getters and constructors
• [ ] make class final, make fields private and final

[ ] @Builder - will not be supported in the current prototype.

Other todos:

• [x] Generic classes
• [x] Actually run compiled code
• [x] Don't generate members that already exist (if having a duplicate is a problem)
• [x] Gradle integration (as subplugin or just a way to enable lombok support)
• [x] Gradle plugin integration test
• [x] Maven integration (as subplugin or just a way to enable lombok support)
• [x] Nullability from annotations. Check if it is inherited from variable definition
