feat: restructure versions

[kptdobe]

WIP

Still TODO: enable new content structure for defined projects to progressively migrate orgs

Fix for #252

This implements the plan defined in #252, including:

• move .da-versions at site level
• get rid of individual empty audit files, replaced by a single audit.txt
• backward compatible, can deal with the 2 .da-versions (legacy and new) and merge to provide the list
• reduce audit logs inside a 30 mins timeframe before writing to audit.txt
• scripts to migrate content
• get rid of Collab parse version (for future new documents)
• same API, no client side code to change

Deployment process:

• once code is deployed and if org has the flag (TBD), audits and versions will start going inside new structure /org/site/.da-versions/<pageuid>/
• list api can deal with legacy and new da-versions content structure (get both, merge and deliver)
• script will be executed to migrate the org - legacy da-versions content structure will be converted to new da-versions content structure
• finally, legacy /org/.da-versions can be deleted

Example of an audit.txt file (reduced for visibily):
