pkg/idutil: reduce conflict rate from 1% to 0.005%
...
Perviously, we only use 8bits from member identification
in id generation. The conflict rate is A(256,3)/256^3, which
is around 1%. Now we use 16bites to reduce the rate to 0.005%.
We can attach the full member id into id generation if needed...

developers access heap profiler with this URL:
http://localhost:12379/debug/pprof/heap

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.

storage: support recovering from backend

We want the KV to support recovering from backend to avoid
additional pointer swap. Or we have to do coordination between
etcdserver and API layer, since API layer might have access to
kv pointer and use a closed kv.

etcdsever: avoid creating member dir before finishing validate bootstrap
...
This commit fixes the issue of creating member dir before validating
the configuration. When member dir exists, it indicates the local etcd
process is a valid etcd member. So we should only create member dir
after we finish configuration validation, joining validation or
discovery validation.

etcdserver: asynchronously notify applier when raft writes finish
...
The raft loop would block on the applier's done channel after
persisting the raft messages; the latency could cause dropped network
messages. Instead, asynchronously notify the applier with a buffered
channel when the raft writes complete.
