Debug aid

[BMurri]

Problem:
The hardest kinds of problems to troubleshoot are the ones were the only information generated is an exit code that may as well be meaningless.

Solution:
Some means of accessing any information produced on the compute node before the task ends.

Describe alternatives you've considered
Providing a solution for #555 is larger in scope and something is needed earlier.

Code dependencies
Will this require code changes in:

• CoA, for new and/or existing deployments? No
• TES standalone, for new and/or existing deployments? No
• Terra, for new and/or existing deployments? No
• Build pipeline? No
• Integration tests? No

Additional context
As envisioned, this is to cover one specific scenario: a very repeatable failure on the compute nodes where no logs of any kind are generated by the task runner, and the batch task ends with a non-zero exit code (usually 10, at the time of this writing).
