Roman Puchkovskiy updated IGNITE-22379:
---------------------------------------
Description:
The user should be able to change the Raft configuration (that is, the nodes
hosting the voting members) of the Metastorage Raft group (MG).
CLI should have 'metastorage reconfigure <new-mg-nodes>' command for doing so.
REST should mirror it.
When reconfiguration is requested, we do changePeers() on the group.
Currently, each node of the cluster hosts either MG peer or MG learner. When a
node sees that MG configuration gets changed, it should convert peer to learner
(or do the reverse) if it's affected by the change.
metastorageNodes in the CMG need to be changed as well.
Might need some design.
