Due to TypeScript bump we should get our tooling decencies updated.

AC:

• bump @typescript-eslint/eslint-plugin and @typescript-eslint/parser to a more recent version (bigger change potential as this will likely yield associated rule config updates)
• use a newer ESLint version, current one is 6.7.2 [Nov 2019]
• use a newer Jest version, current one is 21.2.1 [Sep 2017]
• bump Prettier and related dependencies to a more recent version (lower priority)
