Support instance/replicaset/cluster names instead of UUIDs in the configuration #426

Closed Totktonada closed 9 months ago

See #407 and https://github.com/tarantool/tarantool/pull/8289.

The key difference from the configuration using UUIDs is that instance/replicaset/cluster names are known at the configuration stage.

It is especially important in case of a cluster configuration introduced in https://github.com/tarantool/tarantool/issues/8724.

There is a workaround: use a hash function to generate UUIDs from names. However, it complicates upgrading from old snapshots, where there are no persistent instance/replicaset/cluster names.

I would appreciate hints about possible pitfalls on the road. What else we need to do except just passing the parameters down to box.cfg()?

There are no pitfalls. It just needs to be done and shouldn't be even complicated.
