TAJO-1677: Remove unnecessary messages for the Travis CI build

[blrunner]

Enable -B (batch) mode on the build. This will make the logs shorter since it avoids the dependency download progress logging.

[blrunner]

I've implemented this patch as follows.

• Apply -q parameter for maven : Only show errors.
• Apply -ff parameter for maven : Stop at first failure in reactorized builds
• Apply surefire.useFile=false for maven: This causes surefire to print test failures to standard out.
• Clean up TestSystemMetrics log messages.
• Clean up TajoMaster log messages.
• Fix TestBSTIndexExec:testEqual error.
• Remove RestServer warning log messages.

This change seems to be different to the original intension. This log appears to show which HDFS namenode is used in this TajoMaster.

The first description mentioned that -B will be added to maven option. Was the plan changed?

Please see the following volumes. quite.txt contains all messages from '-q' option. For me, -q seems to be not effective.

Hi @hyunsik

Thank you for your detailed review.
I've updated the patch using your comments.
For your information, I added -q parameter instead of -B parameter. In some unexplained way, -B parameter didn't work as expect.

[blrunner]

I think that the parameter on your desktop seemed like ineffective, because tajo dependencies already had been installed on your desktop. If you see build progress of this PR, you would see that there is no dependency download progress.

You need to recover meaningless changes.

[hyunsik]

As I mentioned in some comments, most of changes are about coding format. You need to recover them. Coding format should be done in a separate issue.
