Description

The scenario is as follows:

1. A streamed RAFT snapshot installation is started
2. Part of data is transferred
3. Snapshot is cancelled (maybe due to the recipient node failure)

As a result, the storage at the recipient node should be in a consistent state. What a 'consistent state' means should be clarified; this could be the state before the snapshot installation started, or it could be some undefined state, but the node would require next snapshot to be installed to function; it should not serve any read/write operations before that.
