[🚀] New plugin / dsl ideas

[Nek-12]

Description

There are new ideas for plugins or DSLs to implement

• Retry Plugin to retry actions. May require passing additional information to the onException callback
• Timeout plugin + DSL. The goal is to disallow intent processing that goes beyond a threshold. May not work for async stores and require a DSL in that case. I think a DSL + plugin combo is the best solution like with job manager, or even to enhance the job manager plugin?
• Metrics like with DropWizard for example. Measure time to reduce the intent, create a state, complete a job. Also need a DSL for arbitrary operations using store logger.
• Conflate plugin to drop duplicate actions and intents (based on equals?)
• Batching or chunking plugin. When there are a lot of intents to process, may want to batch them and wait until the chunk fills. Must be based on time and/or chunk size.
