Auth and OAuth2

The util-simple-auth and util-oauth2 Foxx services have been replaced with the Foxx authand Foxx OAuth2 modules.It is no longer necessary to install these services as dependencies in order to use the functionality.

Old:

'use strict';
const auth = applicationContext.dependencies.simpleAuth;
// ...
const valid = auth.verifyPassword(authData, password);

New:

'use strict';
const createAuth = require('@arangodb/foxx/auth');
const auth = createAuth(); // Use default configuration
// ...
const valid = auth.verifyPassword(authData, password);
