title: Use @HostBindings instead host in angular 4
body: <p>I just try to make animation with angular 4 and I saw tutorial that use host in the component</p>
  
  <pre><code>import { Component, OnInit, HostBinding } from '@angular/core';
  import { AngularFire, AuthProviders, AuthMethods } from 'angularfire2';
  import { Router } from '@angular/router';
   import { moveIn } from '../router.animations';
  
  @Component({
  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css'],
  animations: [moveIn()],
  host: {'[@moveIn]': ''}
  })
  </code></pre>
  
  <p>but it shows me error under the host property
  "[tslint] use @hostBindings and @HostListeners instead of the host property"</p>
