Best practice to sync namespaces & tokens from master to slave

[taiheyp]

Here's the situation:

I've set up kvrocks in sentinel mode - 1 master + 2 slaves, and added some namespaces & tokens on the master node. In case of master failover, I had to add ns & tokens on slave nodes as well, or it would lead to invalid password error (even though the keys had already been synced).

So, is there a "best practice" to sync ns & tokens instead of doing this manually?

Yes, maybe we can support syncing tokens between master and slaves. To see if other guys feel good about this. @apache/kvrocks-committers

[caipengbo]

Yes, we should support this.

I think namespace also is a kind of data, so let's do it🥳

BTY, Can we rethink the design of namespace?

[git-hulk]

Yes, I will post the design proposal recently.

Thanks all for supporting this, please move to issue #1720 if you have any further comments.
