REST API: Introduce Application Passwords for API authentication.

Browse Source 
In WordPress 4.4 the REST API was first introduced. A few releases later in WordPress 4.7, the Content API endpoints were added, paving the way for Gutenberg and countless in-site experiences. In the intervening years, numerous plugins have built on top of the REST API. Many developers shared a common frustration, the lack of external authentication to the REST API.

This commit introduces Application Passwords to allow users to connect to external applications to their WordPress website. Users can generate individual passwords for each application, allowing for easy revocation and activity monitoring. An authorization flow is introduced to make the connection flow simple for users and application developers.

Application Passwords uses Basic Authentication, and by default is only available over an SSL connection.
