add graphql linter and cleanup some groovy scripts

fixes: CCI-115

Test-Plan:
do these steps in one PS:
1 - make some changes that would fail the graphql
2 - add the skip-ci flag in commit message to skip old jenkins
3 - set the GERGICH_PUBLISH = 1 in the main Jenkinsfile
4 - look at patchset 9 for these
