DRILL-6085: Fixed spontaneous vm exits on Travis.

This error occurs sporadically on Travis.

```
Failed to execute goal 
org.apache.maven.plugins:maven-surefire-plugin:2.17:test 
(default-test) on project drill-java-exec: Execution 
default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.17:test 
failed: The forked VM terminated without properly saying goodbye. VM crash or 
System.exit called?
```

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.
