[Engine] Support Dynamic Network Re-configuration

[cjcchen]

The current release version or the version from the master branch does not support reconfiguration. The number of replicas to be deployed is determined by the configuration when deploying to the cluster.

We need to support adding and removing replicas when resilientDB is running in the cluster after deployment.

We can use the following paper based on GeoBFT to allow cluster reconfiguration.
