Hi [~StephanEwen] what are your thoughts on this?

>                 Key: FLINK-4596
>                 URL: https://issues.apache.org/jira/browse/FLINK-4596
>             Project: Flink
>          Issue Type: Bug
>            Reporter: Nagarjun Guraja
> Standalone cluster config accepts an implementation(class) as part of the yaml config
file but that does not work either as cluster level restart strategy or streaming job level
restart strategy
> CLUSTER LEVEL CAUSE: createRestartStrategyFactory converts configured value of strategyname
to lowercase and searches for class name using lowercased string.
> JOB LEVEL CAUSE: Checkpointed streams have specific code to add fixeddelayrestartconfiguration
if no RestartConfiguration is specified in  the job env. Also, jobs cannot provide their own
custom restart strategy implementation and are constrained to pick up one of the three restart
strategies provided by flink. 
> FIX: Do not lower case the strategy config value, support a new restartconfiguration
to fallback to cluster level restart strategy and support jobs to provide custom implementation
of the strategy class itself.
