🚚 Move client folder

[Errorname]

Currently, we have the following folders and files hierarchy:

/
  .circleci/
  .github/
  docs/
  public/
  server/
  src/
  .env
  .env.local.example
  .eslintrc
  .gitignore
  LICENSE.md
  README.md
  doczrc.js
  package-lock.json
  package.json

There is multiple problem with this hierarchy:

• The client is at root level, while the server is in its own folder
• Client files and folders at root level are mixed with unrelated files and folders
• Client package-json scripts handles more than client-only logic (eg: docs stuff)
• It isn't clear where we should add new folders for new "parts" of FAQ (eg: "landing" (landing page/website), "cli" (Create a CLI to simplify developer tasks #183), "status" (status website), "analytics" (analytics website))

This PR proposes the following hierarchy:

/
  .circleci/
  .github/
  client/
  docs/
  server/
  .gitignore
  LICENSE.md
  README.md

Each part will have its own package.json file. (Which is were #183 can be useful)

In the future, with the new "parts" of FAQ, this would look like this:

/
  .circleci/
  .github/
  analytics/
  cli/
  client/
  docs/
  landing/
  server/
  status/
  .gitignore
  LICENSE.md
  README.md
