Turn on no-unused-imports rule and remove all unused imports

[tdonohue]

Description

Small PR which bans unused imports in all classes. We already have LGTM warning when unused imports exist. This officially bans unused imports, to ensure our code is kept small (and easy to tree-shake).

Unused imports will now throw an error when yarn lint is run.
