> Currently, if any errors are encountered during preparation for deploy, the user is taken
to the deploy page and the hosts will be shown as "Waiting" but nothing happens. This is bad
> At a minimum, we should prevent the user from proceeding and display an appropriate error
message if any error is encountered after "Deploy" is clicked, but before we transition to
Step 9.
> We should also think about how a user can recover from this situation.
> At this point, the deploy has not initiated, but certain API calls may have succeeded,
so we may have incomplete info in the database. Currently there's no convenient way to "rollback".
> We can either ask the user to clean the slate by reinitializing the database and try
again (should succeed if the original problem was temporary).
> We can also build more logic in the UI to retry, check if records already exist, etc...
