Description
This is a part of zero down-time upgrades epic: https://github.com/hiero-ledger/hiero-consensus-node/issues/25820
Before a radically new approach to ZDT is started, we should investigate (and improve) what is currently going on during consensus node shutdown and startup. Some shutdown/startup steps can be eliminated at all, some can be significantly reduced in time. Examples are:
* Taking freeze state snapshots
* Replaying events
* OBSERVING status, is in needed at all?
* and more
This ticket is to have a POC to check how far we can get into that direction.
