Refactor the Setting domain to match the proposed architecture

[reyraa]

Description

As a part of the Make Lisk Desktop blockchain agnostic, we should create a domain for user Settings. Said domain is responsible for collecting, storing locally, and displaying user settings.

Acceptance Criteria

According to the TECH proposal document, this domain should have components to:

• Implement togglers that can be used by other components such as navbars, sign-in page and the main settings view.
• Display main settings in a dedicated view.
  • Said view should use commonly reusable togglers and selectors explained above.
• Update the local storage once a setting has been changed.
• Inform users about saving settings.
• Update unit and e2e tests
