title: Flyway callbacks with Oracle compile
body: <p>I try to add before migration and after migration scripts as callbacks to flyway for compiling my views, procedures, functions etc. 
  Is there a possibility to stop it before a migration process or have a rollback when before or after scripts fail (or rather return a warning)?</p>
  
  <p>Cause the only thing I see right now is I receive warnings like this</p>
  
  <blockquote>
    <p>[WARNING] DB: Warning: execution completed with warning (SQL State: 99999 - Error Code: 17110)</p>
  </blockquote>
  
  <p>and it goes on, without stopping.
  I thought about FlywayCallback interface and it's implementation but I'm not entirely sure how it should be done with compiling.</p>
  
  <p>I'm using Spring Boot 1.2.5 with the newest Flyway.</p>
