## 🚀 Feature Proposal

I suggest
1. either to add method `getId()` to interface `WebElement`, or
2. to create interface like `HasId` or `HasIdentity` and make `RemoteWebElement` implement it. 

## Motivation

People often cast `WebElement` to `RemoteWebElement` just to call method `getId()`. 
De-facto all implementations of `WebElement` have method `getId()`. 
For me, it's a problem because `RemoteWebElement` is a class, not interface, and therefore I cannot create a proxy object for it in Selenide. I need some interface with method `getId()`. 

throw new UnsupportedOperationException("`findElement` has been replaced by usages of " + By.Remotable.class);
  }
  /**
   * @deprecated Rely on using {@link By.Remotable} instead
   */
  @Deprecated
  protected List<WebElement> findElements(String by, String using) {
    throw new UnsupportedOperationException("`findElement` has been replaced by usages of " + By.Remotable.class);
  }
  protected void setFoundBy(SearchContext context, WebElement element, String by, String using) {
    if (element instanceof RemoteWebElement) {
      RemoteWebElement remoteElement = (RemoteWebElement) element;
      remoteElement.setFoundBy(context, by, using);
      remoteElement.setFileDetector(getFileDetector());
    }
  }
  
  @Override
  public String getPageSource() {
    return (String) execute(DriverCommand.GET_PAGE_SOURCE).getValue();
  }
  @Override
  public void close() {
    execute(DriverCommand.CLOSE);
  }
  @Override
  public void quit() {
    
    if (sessionId == null) {
      return;
