Kamil Braun 32f4489a18 storage_service: generate CDC streams generation and gossip its timestamp.
Generate a new generation of streams during bootstrap,
insert it into an internal distributed table for other nodes to read
and save its timestamp in the system.local table.

When restarting, read the generation timestamp from the system.local table.

Gossip the generation timestamp.
