Subject: [PATCH] Add jest coverage reporters (#1051)

Summary:
I want to track that data continuously.
HTML is useful to investigate, lcov got loads of external tools that
support it and JSON is quite useful to parse and write to a DB.
Pull Request resolved: https://github.com/facebook/flipper/pull/1051

Test Plan:
```
yarn test --coverage
open coverage/index.html
```
