Add unified merge PoC job templates

 - add PoC templates for unified merge and docker image STAGING jobs
   - unified merge job is triggered by merge submit trigger
   - the triggered docker build and CSIT are based on master
 - use the templates in music
 - restore the original {project-name}-{stream}-docker-golang-shell-daily
   music job
 - remove unsupported "condition" parameters from trigger-jobs
 - change project-specific CSIT to a single job that triggers all the
   plans under the project
 - change snapshot docker build to a single job that is named by
   artifact type (in music's case golang)
 - these changes should not be applied before integration/csit commit
   https://gerrit.onap.org/r/c/integration/csit/+/115170 is merged!
