title: Customize Kibana 7.16 logo or inject custome css or js
body: <p>I'm having a hard time to find the scripts where the logo is defined (navbar logo, startup, login logo ...).
  I've been looking around for ways to change the logo but apparently the kibana project structure has changed significantly in the last builds.
  is there any way to inject a custom js or css to change the default logo of Kibana ?</p>
