Enhanced retry epic

[astubbs]

• Basic retry options - customise message failure retry delay - currently 1 seconds, enable/disable retry
• Retry max reached skip die or dlq or skip? Provide option for max retires, and a call back when reached (potential DLQ) #196
• Retry failure callback (instead or as well as DQL) implemented in Partial implementation of #65 - Custom retry delay provider #92
• Let user function throw retry exception, instead of raw errors which pollute log #242
• DLQ Add a dead letter queue (DQL) implementation #310

Strongly related to #34 - Monitor for progress and optionally shutdown (leave consumer group), skip message or send to DLQ #34

BTW @ismarslomic , did you see ParallelConsumerOptions#defaultMessageRetryDelay? Do you think there should be more documentation around it?

I've added some docs - see 917e469

Custom retry delay duration from supplier function

Possibility to define custom function will be great.

Great! Try out master...astubbs:retry-delay-generator-func linked from the issue and let me know what you think of the api and functionality.
