Call Archiving commands asynchronously from UI to avoid timeouts

[qqmyers]

What this PR does / why we need it: When archiving takes too long (e.g. a 10K file dataset), launching it from the UI can cause a timeout/rollback. This PR updates the code to archive a version from the versions table to run asynchronously and to handle any OptimisticLockException if the dataset changes before the archiving in the background completes.

Which issue(s) this PR closes:

• Closes #

Special notes for your reviewer:
FWIW: This is one of several PRs related to updates being done to improve archiving scalability at QDR and DANS. Some are relatively minor cleanup while others are more significant. I'm submitting them all to avoid drift in QDR's fork and to leverage QDR testing (where all of these are being tested together).

Note: - another PR is coming that will use the asyncCommand call when doing an 'Update-Current-Version' publish action.

Suggestions on how to test this: Regression - confirm that calling an archiving workflow from the versions table still works. Not sure it's practical to try archiving something big enough to see the timeout issue with the current code.

Is there a release notes update needed for this change?: Will create an aggregate one.
