[ovirt-devel] Checkstyle changes in oVirt

[Tal Nisan]

Hey everyone,

We've all reviewed patches that contained imports sorting "noise" caused 
by misconfigured IDEs, I decided to enforce the project's standards 
concerning imports order with the checkstyle plugin.
Achieving this required upgrading checkstyle to version 6.5 and fixing 
the existing violations so we can have a clean baseline to build from.
While I was at it, I fixed the left curly braces position suppression in 
the "uicommon" project to align with the proper standards defined in the 
rest of the project.

Please note that these standards are now enforced at build time and 
patches that violate them will break the build.
A big thank you goes out to everyone who reviewed and commented on the 
patches!
