Docker builds are failing for ccsdk/apps because it is using a snapshot version of parent poms. When this is done, the docker builds remove the '-SNAPSHOT' from the pom.xml before compiling - thus referencing a non-existent version of the parent pom.

2 changes are needed:
1) Guilin version of ccsdk/apps should be using released parent poms, since we are now past M4.
2) Jenkins job for ccsdk/apps docker build should be configured to use the versions plugin to change version, which will cause it not to blindly strip '-SNAPSHOT'. This will allow master branch builds to use snapshot version, which is appropriate.
