This commit adds a functionality of user deletion. It can be invoked
with the new user delete command.
Example usage:
$ ETCDCTL_API=3 etcdctl user delete usr1
Alarms are events that nodes can use to relay health information to
the rest of the cluster. A node may Activate an alarm and that alarm
will stay set until Deactivated.
This commit adds a new subcommand "user add" to etcdctlv3. With the
command users can create a user for the authentication.
Example of usage:
$ etcdctlv3 user add user1
Password of user1:
Type password of user1 again for confirmation:
This commit adds a new package auth. Its role is persisting auth
related metadata. This commit also connects its main interface
AuthStore and v3 server.

And resp.Header.Revision should be from the one in storage
when we just do range, because there is no storage data
change.
When raft broadcasts a Grant to all nodes, all nodes must
agree on the same lease ID. Otherwise, attaching a key to
a lease will fail since the lease ID is node-dependent.
Basic support for lease operations like create and revoke.
We still need to:
1. attach keys to leases in KV implmentation if lease field is set
2. leader periodically removes expired leases
3. leader serves keepAlive requests and follower forwards keepAlive
requests to leader.
We should open real txn for applying txn requests. Or the intermediate
state might be observed by reader.
This also fixes#3803. Same consistent(raft) index per multiple indenpendent
operations confuses consistentStore.
We have a structure called InternalRaftRequest. Making the function
shorter by calling it processInternalRaftReq seems to be random and
reduce the readability. So we just use the full name.
