[EAGLE-740]Fix eagle-query checkstyle warnings

http://issues.apache.org/jira/browse/EAGLE-740

[haoch]

Classes under org.apache.eagle.query.antlr.generated is automatically generated by antlr, so suggest to exclude it from checkstyle and keep the original code.

[koone]

revert eagle-antlr and exclude Classes under org.apache.eagle.query.antlr.generated from checstyle
@haoch could you please check again

[haoch]

Could you please rollback the code format of files under org.apache.eagle.query.antlr.generated too?

[koone]

@haoch the last commit is already roolback the code format

[haoch]

@koone thanks

[haoch]

@koone As the PR changed too many files, please it may take a few days for reviewing.

[jhsenjaliya]

@haoch , do you need any help on reviewing this?
@koone, Can you please rebase this PR ? Thanks

[jhsenjaliya]

Hi @koone, This would be good to add in 0.5 branch, would you have time to rebase this and address comments from @haoch ? Thanks

[jhsenjaliya]

I spent lot of time in rebasing this, but eventually it got very confusing since there are lot of files ( ~1500) to be rebased, which i did (jhsenjaliya:EAGLE-740-rebased) but there are multiple layers of rebase needs to be done, and i afraid i cant pick the right candidate wherever there are conflicts. so I am leaving this aside for 0.5 release, and we can get to this afterwards. this is important and we should take this change eventually. Thanks
