title: How can you make preinstall hooks to wait for finishing of the previous hook?
body: <p>I have 2 preinstall scripts that should run sequentially.
  They have obviously different weights
  The second script must have the first one to finish running.
  Is there anyway to make helm support this behavior?</p>
  
  <p>And also for bonus point can you make a pre-install hook to block till the object becomes ready?</p>
  
  <p><strong>The scenario is as follows:</strong></p>
  
  <p>You have a database, and an application. </p>
  
  <p>The setup is:</p>
  
  <ol>
  <li>create a database (deployment),</li>
  <li>create a database (service),</li>
  <li>ran a script that creates all the database users on that db (job)</li>
  <li>start the application server (deployment).</li>
  </ol>
