raft: add removed
...
The usage of removed:
1. tell removed node about its removal explicitly using msgDenied
2. prevent removed node disrupt cluster progress by launching leader election
It is set when apply node removal, or receive msgDenied.

raft: stop tickElection when the node is not in peer list
...
This prevents the bug like this:
1. a node sends join to a cluster and succeeds
2. it starts with empty peers and waits for sync, but it have not
received anything
3. election timeout passes, and it promotes itself to leader
4. it commits some log entry
5. its log conflicts with the cluster's

Configure is used to propose config change. AddNode and RemoveNode is
used to apply cluster change to raft state machine. They are the
basics for dynamic configuration.

raft: add conf safety
...
To make configuration change safe without adding configuration protocol:
1. We only allow to add/remove one node at a time.
2. We only allow one uncommitted configuration entry in the log.
These two rules can make sure there is no disjoint quorums in both current cluster and the
future(after applied any number of committed entries or uncommitted entries in log) clusters.
We add a type field in Entry structure for two reasons:
1. Statemachine needs to know if there is a pending configuration change.
2. Configuration entry should be executed by raft package rather application who is using raft.
