Store log output in datamodel extension

[stscijgbot-jp]

Issue JP-3773 was created on JIRA by Tyler Pauly:

JWSTDMS-485 documents the desire for an HST-like trailer file which stores the processing output log during science product generation. JSDP-2860 is tracking SDP's work to generate such an external file, while this ticket is to explore the storage of the log output of the CAL pipeline in a datamodel extension/object/attribute. Such an attribute already appears to exist and is in use for exactly this purpose in Roman processing, such that this work should be straightforward to implement on the JWST side; the primary blocker/investigation remaining is in understanding what information needs to be scrubbed to maintain IT security. From DMS planning, scrubbed information should be:

- Node/machine names
- IP addresses
- usernames who have access to those machines
- filesystems paths

Comment by David Law on JIRA:

Adding a note that this is a indeed a feature still requested by users; I was discussing this at a science meeting just this week.
