title: ASP.NET5 beta8 IServiceCollection changes
body: <p>After updating my project to recently released ASP.NET 5 beta8 I've found that <code>IServiceCollection</code> no longer contains definition for <code>ConfigureIdentity</code> and <code>ConfigureIdentityApplicationCookie</code>.</p>
  
  <p>So previously written code like</p>
  
  <pre><code>services.ConfigureIdentity(o =&gt;
      {
          o.Password.RequireUppercase = false;
          o.Password.RequireNonLetterOrDigit = false;
      });
  
  services.ConfigureIdentityApplicationCookie(o =&gt; o.LoginPath = "/Admin/Users/Login");
  </code></pre>
  
  <p>can't be compiled anymore.</p>
  
  <p>Google search brings no result, I suppose it is because only one day has passed since beta8 release.</p>
  
  <p>Has anyone found workaround for this? How should identity options be configured in beta8?</p>
