Engine: Deployment Activation/Deactivation

[jjoderis]

Summary

Added functionality to the engine that allows activation and deactivation of processes which can be used to allow/disallow typed start events to automatically trigger new instances

Details

• added new rest endpoint that can be used to activate/deactivate specific versions of processes
  • if a version is activated all other versions of the process are deactivated
• Fixed: if a process with an active deployment is removed from an engine the active deployment keeps spawning new instances since it is not removed from the execution environment
• Changed the deployment behavior of the MS
  • when a version of a process is deployed it gets activated automatically
  • when the MS finds that a version is already deployed it will not deploy it another time
  • when the MS finds other engines that already have deployments of another version of the process they are preferred for the deployment of the new version
  • the MS tries to deactivate all deployments of the process on engines that the new version is not deployed to
