Service - Basic Auth File User Store

An HTTP service/resource can be secured using Basic auth and optionally by enforcing authorization. Then, it validates the Basic auth token sent in the Authorization header against the provided configurations. This reads data from a file, which has a TOML format. This stores the usernames, passwords for authentication, and scopes for authorization.
Ballerina uses the concept of scopes for authorization. A resource declared in a service can be bound to one/more scope(s).
In the authorization phase, the scopes of the service/resource are compared against the scope included in the user store for at least one match between the two sets.
Config.toml has defined three users - alice, ldclakmal and eve. Each user has a password and optionally assigned scopes as an array.

For more information on the underlying module, see the Auth module.

It is optional to override the authentication and authorization configurations at the resource levels. Otherwise, the service auth configurations will be applied automatically to the resources as well.
