Document manual process for removing WARCs

[edsu]

@peterchanws has occasionally needed to remove WARC files from SWAP. This isn't a common occurrence, and there isn't an obvious place to trigger it in Argo, so this can be a manual process. We should document the process in DevOpsDocs.

I think we had the wrong GitHub handle for you, @peterchanws.

Should this be assigned to @peterchanws?

The use case is if we have WARCs with PII. This is a future use case, not existing need. We think this process involves removing the WARC from web-archiving-stacks and re-indexing all WARCs (or remove lines from indexes that reference the problem WARC). This is a hand-editing process right now, so a script to do this would be an improvement.

We'll wait for future pywb improvements to access logic.
