Description

Currently, if a checkpoint is triggered while a task s not in a RUNNING state the following message is logged:

Checkpoint triggering task {} of job {} is not being executed at the moment.

We can improve this message to include the actual task state to help diagnose problems.

This message is also a bit ambiguous, as "being executed" could mean many things, from not "RUNNING", to not being "DEPLOYED", or to not existing at all.
