Improve and Extend EndOfBlock Message Handling to Utilize `ResendBlock`

[ata-nas]

Story Form

As a Publisher Manager
I want to improve and extend the handling of the EndOfBlock message to support the ResendBlock message
So that I will be able to ask for a block to be resent

Technical Notes

• Extend Support for the EndOfBlock Message in Stream Publisher Plugin #2159 introduces basic handling of the EndOfBlock message
• We need to extend the handling to respond with ResendBlock message when needed in order to be able to ask for a block to be resent after the end of a block.
