Description

Motivation and all preliminary details could be found in the investigation ticket.

In this ticket we provide plan for the development:

• Move all logic from DisasterRecoveryManager#resetPartitions which uses requests with operationIds, RECOVERY_TRIGGER_KEY and writing such requests to MS, to a separate class, let's name it DisasterRecoveryService
• Let's place it in new module that is earlier in the hierarchy than distributionzones module
• New DisasterRecoveryService should also provide logic of registering handlers for DisasterRecoveryRequest
• Handler for GroupUpdateRequest must be implemented in the new introduced module
• Handler for ManualGroupRestartRequest must be implemented in table.distributed.disaster
• All logic of globalPartitionStates(), localPartitionStates must be also moved from table.distributed.disaster to the new module
• That means that we need to refactor also org.apache.ignite.internal.partition.replicator.network.PartitionReplicationMessageGroup.DisasterRecoveryMessages and move it to new module, so it will be possible to call logic of retrieving partitions state from distributionzones
