Example URL: http://host:port/login
POST to log in and generate/review session cookie.
Fusion sets "Set-Cookie" with field name "fdfusionsessionid" and associated value in headers of its responses to keep the session. In turn, all browser (or some client) request headers should contain "Cookie" with field name "fdfusionsessionid" and associated value in header.
Result: Redirection to the FireDaemon Quick Stats page after a successful login. If the user is unauthorized, this call redirects the user to the login page.
