* Revert "Enable UniqueRetryJobMiddleware even when called from sidekiq worker (#4836)"
This reverts commit 6859d4c028.
* Revert "Do not execute the job with the same arguments as the retry job (#4814)"
This reverts commit be7ffa2d75.
* add redis-namespace gem
* namespace redis usage
* refactor redis namespace code to be less intrusive
previously : would be prepended to keys when the
REDIS_NAMESPACE env var was not set
now if it is not set the namespacing functions are
not used at all, which should prevent disruptions
when instances update.
* fix redis namespace variable style in streaming js
* remove trailing space
* final redis namespace style fix
