## What
Harmonize and clean-up yarn test commands convention.
## Why
Current strategy to filter integration tests from unit tests was cumbersome to maintain. Also, some packages declared `test:unit` which ended up being an alias to `test`.
## How
* Remove all occurrences of `test:unit`
* Rename all `test` commands under `/integration-tests/**/package.json` to `test:integration`
* In the root `package.json`, rewrite `test:integration` command to run `turbo run test:integration`
* In the root `package.json`, remove filtering on the `test` command
* Introduce a new `test:integration` task in the Turborepo config.
