Config: strict/non-strict consumption

[bnayae]

When inheriting an interface.
Producing may happen on the level of the derived interface, while consumers can be at the base interface level.
configuration should determine whether to hang on a non-exist method.
Hanging may be useful when another consumer consumes the rest of the messages.

• Strict
  • Should indicate whether it is an error or waiting
  • Waiting: should release the pending if it does not exist
    • When releasing pending should await and start consuming again with incremental chunk size
