Move files from OSS option 1 to Option 2

Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/224

*This diff is part of a stack which has the goal of "buckifying" D2 (https://github.com/facebookresearch/d2go/commit/87374efb134e539090e0b5c476809dc35bf6aedb)Go core and enabling autodeps and other tooling. The last diff in the stack introduces the TARGETS. The diffs earlier in the stack are resolving circular dependencies and other issues which prevent the buckification from occurring.*

This diffs moves a few files from using the pattern 1 of open source overriding to the pattern 2, using the decorators.
