0d7c43d885 *: add a Advance interface to raft.Node 
Node set the applied to committed right after it sends out Ready to application. This is not
correct since the application has not actually applied the entries at that point. We add a
Advance interface to Node. Application needs to call Advance to tell raft Node its progress.
Also this change can avoid unnecessary copying when application is still applying entires but
there are more entries to be applied.

791b2fd503 *: handle panic and fatal more consistently 
1. etcd fatals if there is critical error in the system and operator should
do something for it
2. etcd panics if there happens something unexpected, and it should be
reported to us to debug.

5ed5d44652 etcdserver: print out initial cluster members 
It is moved from etcdmain pkg because the line should only be printed out
when etcd bootstraps at the first time.

It is a critical error to etcd, and etcd is not able to recover it now.

55c92ad456 *: create ID type 
This creates a simple ID type (wrapped around uint64) to provide for
standard serialization/deserialization to a string (i.e. base 16
encoded). This replaces strutil so now that package is removed.

719c57a29d proxy: retrieve ClientURLs from cluster 
This is a simple solution to having the proxy keep up to date with the
state of the cluster. Basically, it uses the cluster configuration
provided at start up (i.e. with `-initial-cluster-state`) to determine
where to reach peer(s) in the cluster, and then it will periodically hit
the `/members` endpoint of those peer(s) (using the same mechanism that
`-cluster-state=existing` does to initialise) to update the set of valid
client URLs to proxy to.

This does not address discovery (#1376), and it would probably be better
to update the set of proxyURLs dynamically whenever we fetch the new
state of the cluster; but it needs a bit more thinking to have this done
in a clean way with the proxy interface.

Example in Procfile works again.

line. IDs are consistent if the URLs are consistent.
