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:
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.
Using Go-style import paths in protos is not idiomatic. Normally, this
detail would be internal to etcd, but the path from which gogoproto
is imported affects downstream consumers (e.g. cockroachdb).
In cockroach, we want to avoid including `$GOPATH/src` in our protoc
include path for various reasons. This patch puts etcd on the same
convention, which allows this for cockroach.

This commit also regenerates all the protos, which seem to have
drifted a tiny bit.
