An exploration into temporal collab spaces (Loop DB workstream)

[vladsud]

This is a prototype that explores what it would take to create temporal collab spaces. It allows to leverage complex components that depends on collab capabilities (in this prototype - single DDS), at the same time be able to transition to "flat" representation serialized as a cell value in SharedMatrix, and thus destroy more expensive collab state when collaboration is not required.

This is just a prototype, but with exception of some Pri1s & Pri2s mentioned in the code, it works and close to completion. That said, many of its stress tests are not passing as they discover existing bugs in Shared Matrix that must be fixed.

It will not go as is, as it needs to be modified to leverage data stores (not DDSs) as "channels", which is big change on its own. As such, this prototype is here only for reference.   The following internal MSFT document describes proposal: https://microsoft-my.sharepoint-df.com/:w:/p/vladsud/EfUMOWC2zPdMoFggka4ZSGUBiKJZs9mhQr-3bwPorUELag?e=PZRGqd
