Description

After DRILL-4286 changes some of the newly added unit tests fail with

Drillbit is disallowed to bind to loopback address in distributed mode.

List of failed tests:

Tests in error: 
  TestGracefulShutdown.testOnlineEndPoints:96 » IllegalState Cluster fixture set...
  TestGracefulShutdown.testStateChange:130 » IllegalState Cluster fixture setup ...
  TestGracefulShutdown.testRestApi:167 » IllegalState Cluster fixture setup fail...

This can be fixed if /etc/hosts file is edited.

Though these changes are required on production during running unit tests I don't think this check should be enforced.

For documentation
drill.exec.allow_loopback_address_binding -> Allow drillbit to bind to loopback address in distributed mode. Enabled only for testing purposes.
