[DRAFT] Attempt fix Jms watermark

[Abacn]

Originally, the problem was watermark set to Instant.now() at initialization and after finalizing every non zero checkpoint mark. This had two issues

• watermark can be too new for incoming data, when checkpoint is not finalized
• watermark does not increase when there is no incoming data for a while

This PR attempted to address both.
