Review request for Aurora.


Bugs: AURORA-1138
    https://issues.apache.org/jira/browse/AURORA-1138


Repository: aurora


Description
-------

To make sure the vagrant system is up and running successfully
we need to fail the provisioning steps when errors strike.

Bash -e flag tells bash to exit on any non-zero exit from any
command (with excpetions), giving us the early exit needed.

To ignore errors add '|| true' after the command to ignore
failures from.

After the provisioning steps complete the aurora-scheduler does not start due to 

`Could not find or load main class org.apache.aurora.scheduler.app.SchedulerMain`

I'm trying to figure out why, but gradle is new to me so I'm not sure why it is not being built/included in the .jar files.
