* Update docs/submodules/releng from branch 'master'
  - Apex: fixes snapshot promotion be variables
    
    Since job names changed during the migration to multijob, we need to
    update the scripts which assume the the snapshot type is part of the job
    name.  Moving them to be jjb variables instead and not rely on job name.
