DRILL-6085: Fixed spontaneous vm exits on Travis.
This error occurs sporadically on Travis.
```

```
I believe the issue is caused by the fact that our travis containers only
have 4gb of memory and our test vms are given up to 4 gb of direct memory and
heap memory (for a total of up to 8gb). Because we are promising more memory
than we have it seems we occasionally hit the limit of our 4gb vm. I have added
the ```sudo: "required"``` option to travis.yml which increases the amount of
memory in the container to 7gb.
The vm exits occurred about 30% of the time lately before this change for
me. With this change I ran 5 consecutive builds without a vm exit.
