Remove all Raft protocol code

Removed all Raft-related code as it was not working properly:
- Removed VSRaftProtocol.java implementation
- Removed all Raft test files
- Removed Raft example/demo files
- Removed Raft documentation
- Removed Raft simulation files (.dat)
- Removed Raft scripts
- Updated VSRegisteredEvents to remove Raft registration
- Updated SimulationBuilder to remove RAFT constant
- Updated SimulationFactory to remove Raft methods
- Updated SimulationBuilderTest to remove Raft tests
- Updated pom.xml to remove Raft test configurations

The protocol had issues with leader election not completing in GUI mode.
