Update git submodules

* Update docs/submodules/ccsdk/cds.git from branch 'master'
  to 2ef7909fd0b9d12a7fe1619639e787c5ee0cf4c3
  - Merge "Fix Sonar Jenkins job"
  - Fix Sonar Jenkins job

    Updated pom.xmls of modules that do not contain 'src/main' directory
    to skip Sonar scan.  This allows Sonar scan to complete for the rest
    of CDS.  Need to revisit these modules to see whether they should
    really be skipped or if sonar properties (e.g. sonar.sources) should
    instead be tailored.
