Summary:
At the moment, this test will fail. There are currently two issues with it:
- Cap'n Proto limit exception might occur
- `db.Reset()` method can hang (deadlock)
The first issue should be resolved by migration to SLK and we are currently
working on the second one. The test will land after those are fixed.

Summary:
Added a new config parameter, replication timeout. This parameter sets the
upper limit to the replication phase and once the timeout exceeds, the
transaction engine stops accepting new transactions.
We could experience this timeout in two cases:
1. a network partition
2. majority of the cluster stops working

Summary:
Added index creation and deletion handling in StateDelta.
Also included an integration test that creates an index and makes sure that it
gets replicated by killing each peer eventually causing a leader re-election.

Summary:
I've refactored the integration test for HA so we can reuse the common
parts like starting/stopping workers.
I've also added a test that triggers the log compaction and it checks that the
snapshot that has been transferred is the same as the origin one.
