   ## What is the purpose of the change
   
   Current best practice when deploying Flink applications to production is to set a custom UID, using DataStream#uid, so jobs can resume from savepoints even if they job graph has been modified. Flink should contain a configuration that can allow users to fail submission if their program contains an operator without a custom UID; enforcing best practices similarly to #disableGenericTypes. 
   
   ## Brief change log
   
   Adds a new configuration #disableAutoGeneratedUIDs which will fail job submission if there are any operators without a custom uid.
